Industrial Microwave Technology

Heat-drying has become an important procedure in almost all fields of industrial processing.  Apart from the popular conventional procedures based on conduction, convection, or infra-red radiation, heat-drying utilizing microwave energy is an attractive solution to many problems in process technology. In microwave drying, the heat is generated by directly transforming the electromagnetic energy into kinetic molecular energy, thus the heat is generated directly within the material to be dried. Microwaves produce heat by vibrating water molecules, almost a billion times per second.  The resulting friction converts the radio energy to heat energy and vaporizes the water. As compared to conventional drying methods, microwaves penetrate into much greater depths. If the penetration depth is bigger than the product dimensions, this is so-called volume heating with the following advantages

A further field of application for microwave dryer in addition to existing conventional systems is the end drying to low residual moisture levels down into the ppm range. When we apply industrial microwave technology, we should notice there are other properties of the product that need to be considered, such as its capacity to absorb water, shape and size of the product, as well as the temperature-dependent dielectric properties interacting with the microwaves. To obtain optimal drying results, it is necessary to develop a microwave system that takes all the properties of the entire system into account.

In recent years we have work closer with research organization and universities to provide novel system and equipment for all kinds of drying application. We have test machine available to evaluate your material and demonstrate that microwave processing will produce a suitable product for your demands.

Microwave Dry and sterilize Starch

In some humidity area, company need to dry starch from 12% moisture content down to 6%-7%.Conventional heating and drying solutions approach starch from the surface, applying heat only to the outside edge. Traditional technique fast dehydrates surface moisture, but it is inefficient to dry low moisture content of material or remove liquid trapped inside the material.

The microwave heating occurs instantaneously and can be very fast, although it does not have to be. However, the speed of microwave heating can be an advantage, and is often possible to accomplish in seconds and minutes what could take minutes, hours, and even days with conventional heating methods

Microwave Heating and Drying Machine Advantage:

Microwave systems are more compact, requiring a smaller equipment footprint.

Microwave energy is precisely controllable and can be turned on and off instantly, eliminating the need for warm-up and cool-down. Lack of high-temperature heating surfaces greatly reduces the amount of product that is burned or overheated.

The use of industrial microwave systems avoids combustible gaseous by-products, eliminating the need for environmental permits and improving working conditions.

Compared to conventional heating, microwave heated food products tend to retain a higher percentage of flavors and nutrients

It can also sterilize starch during the drying purpose to avoid the

Microwaves heating machine reduces production run times and both cleaning times and chemical costs.

Except to dry starch, microwave drying machine is also used to dry soybean, sesame, rice, flour and others. 

Microwave Heating System

Microwave Heating System providces a form of electromagnetic energy where polar molecules as well as free ions in receptive materials respond to these fields through creation of molecular friction that results in heat throughout mass of material. Therefore, the microwave sterilization/pasteurization technology used has helped many spice and food companies to develop new food products which have not been possible till now because of limitation of severe heat in conventional retorting. Some of the advantages of microwave heating over conventional heating methods include high speed operations and space saving operations that reduces scrap and saves on labor. Here, with microwave energy penetrating to generate heat internally and at surface of treated material, it overcomes time and temperature limitations and produces high quality product even when materials that are being processed are fairly thick. Some of the benefits provided using technology includes:

Provides instantaneous electronic control as microwave power levels can be easily adjusted electronically in fraction of second

Microwave equipment is readily adaptable to automated systems and to data logging programs

Allows high process efficiency & operation speed as microwave processing requires fewer BTU's for same/better results than conventional equipment

Keeps food and spice original flavor and aroma during the pasteurization

 Microwave processing is clean as it is a inherently dry and fumeless process and is also environmentally clean specially in comparison to processes requiring additional media for heat transfer.

Microwave electromagnetic wave directly work on the water molecular saving the heat conduction stage to accelerate the drying speed.

Industrial Microwave drying method is an alternative and efficient drying solution for corrugated box, paper tube and other paper material.

Carrageenan Dehydration Machine

Carrageenans or carrageenins are extracted from red edible seaweeds. They are widely used in the food industry, for their gelling, thickening, and stabilizing properties. Their main application is in dairy and meat products, due to their strong binding to food proteins. There are three main varieties of carrageenan, which differ in their degree of sulphation. Kappa-carrageenan has one sulphate group per disaccharide. Iota-carrageenan has two sulphates per disaccharide. Lambda carrageenan has three sulphates per disaccharide. Carrageenan is avegetarian and vegan alternative to gelatin in some applications or may be used to replace gelatin in confectionery.

Use of carrageenan in infant formula and found that the additive was ‘not of concern’ in infant formula as food for special medical purposes at concentrations up to 1000 milligrams per liter.   The use of carrageenan in infant formula, organic or otherwise, is prohibited in the EU for precautionary reasons, but is permitted in other food items. In the US, it is permitted in organic and non-organic foods, including juices, chocolate milk, and organic infant formula. The application is including Desserts, ice cream, cream, milkshakes, yogurts, salad dressings, sweetened condensed milks, Soy milk, Vegetarian hot dogs, Personal lubricants, Pet food, Biotechnology, Diet sodas.

MAX Industrial Microwave manufactures the continuous furnace microwave which can quickly dry and sterilize carrageenan powder. Comparing to hot air drying and infrared, microwave is more efficient, especially in the lower moisture content, microwave vibrates the material water molecular to exert the heating energy. On the other hand, microwave sterilizes the microbes to keep food in a clean condition.
