How to Choose Industrial Microwave

When we talk about microwave, household microwave might appear in our brain. The home microwave oven is often used for heating food or leftovers. However, we might be not familiar with industrial microwave because it’s big size and larger microwave power. There are some frequent questions when people want to know the industrial microwave

 

What's the microwave?

 

As a kind of electromagnetic radiation, microwave has a wide range of applications such as radar, communications, and the best known by most of us, heating, drying and cooking etc. But, microwaves is different from nuclear radiation or ionizing radiation. So we could know the microwave is non-ionizing radiation which means that they pose no lasting influence, it’s totally opposed to nuclear radiation or ionizing radiation which can permanently change exposed materials.

 

What's the difference between home microwave and industrial microwave.

 

MAX Industrial Microwave is equipped with temperature sensor which would detect material temperature and reflect back to PLC touch screen so operator could instantly control processing temperature to avoid over-temperature. And exhaust system could quickly discharge moisture out of machine because of high humidity in the microwave chamber. And industrial microwave control and adjust its power output based on the temperature data. while our industrial microwaves come in a lot of configurations such as continuous flow, water cooling temperature sensor etc.

 

What's the lifespan of industrial microwave?

 

When we mention machine lifespan, we generally talk about magnetrons and industrial power because other parts are very robust and have a lifespan. Magnetrons typically have about 5000 working hours to 8000 working hours, then then it will usually start to deteriorate just like our cellphone battery. The industrial power which offer high voltage to magnetrons has a longer working hours. Right now, we use integration power which replace old transformer, diode and capacitor. The integration industrial power can save 12% energy consumption comparing to traditional transformer. Also, the belt may also need change depends on the working condition, any scratch or twist would cause belt destroy, and the unexpected pieces of metal might cause spark which could burnt the belt. The regular maintenance can be expected to last longer service time

 

Does machine require accessories parts?

 

The answer is yes. Apart from electricity, we also need set up water cooling system for magnetrons and exhaust fan for discharging moisture that come from original products. According to the machine power, we match with different water flow volume water cooling system which help machine to cope with harsh environment like hot weather and high humidity as well as assure machine longer and stable working condition. We choose the right model exhaust fan that greatly get rid of moisture out of machine chamber and avoid moisture building up and dropping back on the belt. Also, we install a cooling fan that can continuously send cooling air to electrical components in order to reduce the temperature of components. Sometimes, we collect the output product which is about 55 degree Celsius from microwave heating, the high temperature of product is not able to go thorough the packing machine. So we should add an extra cooling line in the end of microwave machine in order to reduce the products temperature, and the products could be immediately packed after microwave heating process.

 

Why should we use microwave ?

 

When we talk about microwave advantages, we must mention that microwave has a higher drying capacity, the strong and bulk microwave energy can quickly dehydrate or heat material typically 5~6 times faster than conventional dryer. The unique heating penetration features can easily dry the core part of material which dramatically shorten drying time, especially for some products that are hard to dry the inside part. Reliable intelligent program poses an uniform heat distribution and make sure machine continuously operate without human intervention. On the other hand, microwave machine can upgrade your workshop environment because it offers a clean circumstance with little to no emissions and thus permitting is usually not required due to lack of combustion.

 

How to choose industrial microwave for your application ?

 

There are some factors we need think about prior to get an industrial microwave. Firstly, the electricity consumption, we must admit that the electricity is an expensive resource in some areas and countries. Meanwhile the target material might also has a low value. Based on above two conditions, traditional drying solution might be more cost-efficient. Secondly, some material does not positively absorb the microwave energy like Teflon material and some special material so we need other drying solution to process them.

 

Generally speaking, microwave machine is often used for tempering frozen meat block & dairy products, roasting nuts (soybean, black beans, peanuts and cashew nuts), cooking prepared foods, extending food products shelf life, pasteurization and sterilization, processing of raw food stuffs like shrimp: drying chemical material to lower moisture content like battery material (under 1%), re-heat ready package meal, insects drying, curing application etc.

 

Therefore, we need do a trial to figure this out, we can get some sample to make a test on a medium scale or pilot testing in order to learn how material behave in the microwave. MAX Industrial Microwave welcome you visit us and get material processed on our pilot machine. After the trial process, we could customize the machine capacity to meet with your demands.

 

Could we choose different power of machine?

 

MAX Industrial Microwave is able to customize both batch oven and conveyor belt to handle with different input products. Batch microwave oven require operator regularly put and take out of material each batch, and oven machine typically process material which is less than 20kg/h. But tunnel conveyor microwave could continuously process material throughout feeding hopper with less labor. For most applications, we suggest a continuous tunnel. And we manufacture machine power from minimal 6kw to 180kw. Generally, we offer our clients a wide range of model of machine to meet with a wide range of demands. Our Microwave system has been engineered to significantly exceed our clients’ expectation. If you could show us your building layout, we could offer possibilities for laying out our microwave system to fit the workshop.

Microwave Drying Influence

Traditional heating or drying methods like steam, hot air, coal burning are used as heat conduction function from the outside to inside of material, Thus, the heating and drying time is a bit longer, and the efficiency is lower, the heating result is not very homogeneous, and operate sometimes need pre-heat oven which cause energy wastage. The invention of microwave drying equipment has precisely dealt with the above problems, and is now widely used in food, chemical, grains and pharmaceutical industries.

 

Microwave radiation has the selective heating characteristic. For example, if material has a large moisture content that is water molecular polarity is very strong, it is more easily by microwave heating. So the higher the water content of products/ material quickly absorb microwave energy, which accelerate drying speed. When the moisture content decreased, the ability to absorb microwave was also reduced. The feature contributes to the drying result uniformly.

 

In the pre-drying, the moisture content in the products is very high, equipment of microwave power on the influence of the drying effect is high(water is the best medium absorbing microwave). When the time goes by, most of the microwave energy is absorbed by water, and moisture migration and evaporate quickly. In the later stage of drying, with the decrease of moisture of material, the microwave energy required is also less, and the power of microwave equipment can be diluted appropriately. But there are many products that are not able to dry under a high temperature so we should apply the microwave vacuum drying equipment or control processing temperature: in the condition of vacuum, the boiling point of water is reduced, vitamins and other nutrition are properly maintained. Under the environment of the relative lack of oxygen in food drying can reduce or even avoid the fat oxidation, Browning or other pigment oxidation, etc. Or we could install the temperature sensor which control heating temperature under a proper and low temperature.

 

The microwave drying machine is a non-standard product. The specific power size and design need to be combined with the product process so that the effect will be maximized. MAX microwave dryer can be customized to meet with our clients’ expectation.

Agriculture Bran Microwave Stabilization

People recently realize the important agriculture bran is good for our health. Daily consuming some bran can reduce the risk of cardiovascular diseases and high blood pressure. How to treat the rice & wheat bran become an important part for many food company. Let’s see the microwave heating treatment for rice bran.

Experimental evidence obtained from physical, thermal and nutritional studies have shown that microwave heating is an effective method for the inactivation of lipase that is responsible for rice bran degradation and instability. Rice bran, stabilized by microwave heating at 2450MHz for 3 min was found to be stable for up to four weeks in storage. Free fatty acid (FFA) content of microwave stabilized bran increased from 4.0% to 4.9% in long grain rice bran and from 4.6% too 6.25% in medium grain rice bran, even when stored under unfavorable storage conditions (33°±2°C, 75±5% relative humidity). In contrast, increases in the untreated bran FFA ranged from 4.0% to 68.3% and 4.6% to 56.8% in long and medium grain bran, respectively.

Based on the experiment, MAX Industrial Microwave manufactures conveyor belt s2450Mhz microwave to heat wheat bran and raw rice bran. Comparing to other treatment, there is no doubt that microwave treatment is an efficient way in which not only quickly process rice bran, but also keep much nutrition.

The rice bran samples were subjected to eight treatments including hot air oven heating, micro wave heating and ethanol to study their effect on rice bran stability. Different parameters including rancidity of rice bran oil and its' nutritive values were determined on zero, 30 days and.

180 days of storage at room temperature (32°C) after applying these treatments. The treatments were(1) Control, (2) Autoclave and subsequently drying at 80℃overnight, (3) Hot air oven at 130℃for 20 minutes,(4) Hot air dryer at 180℃for 5 minutes, (5) microwave at 900 watt for 1 minute, (6) microwave at 900 watt for 1.5 minute, (7) microwave treatment for 2.5 minutes,(8) Soaking with 80% Et-OH for 6 hour and after filtration, drying of the RB in the oven 80℃and subsequently grinding into powder form. After completion of the treatments, all the containers were kept in room temperature(32℃) and the following biochemical parameter were estimated at 1 day, 30 days and 180 days interval.

The nutritional quality of rice bran (RB) differs significantly at different days of preservation at room temperature (32°C) (Table 1). The antioxidative activity (AA) of crude ethanolic extracts was determined by DPPH assay methodology. At the first day of treatment, the highest AA (87.53% inhibition) was found from treatment 6 (microwave heating for 1.5 minutes) followed by treatment 7 i.e. microwave heating for 2.5 minutes (85.39% inhibition) and after 180 days of preservation, both of the above treatments performed better (highest AA: 83.4 and 83.53% inhibition respectively) as compared to others

From the present work, it could be concluded that Microwave treatment for 2.5 minutes gave very good results in respect of minimum rancidity and higher nutritional value, when we preserved it for 180 days. Actually, preservation of rice bran is necessary because the value added product like rice bran cake, biscuit can be prepared by this stabilized bran and these products are very good for our health especially for cardiovascular diseases.

Microwave rice & wheat bran stabilization machine is widely recognized by many agriculture farms and food companies. It is also a totally environmentally-friendly machine without any pollution so the microwave heating machine significantly improves working condition.
