Development Trends of Various Food Dryers

Dry food is a necessary measure to improve food storage and shelf life. The performance of the dryer directly affects the quality and value of dried food. In recent years, China has developed a variety of versatile, high efficiency, low energy consumption, strong adaptability of the dryer. Vegetable drying equipment uses high temperature and steam for heat exchange, so that normal temperature air becomes high temperature and dry hot air, reaching temperatures above 120°C. Can be dehydrated on cabbage, spinach, garlic, onion, green bean sprouts, pumpkin slices, radish slices, potato chips, etc. The temperature can be arbitrarily controlled. The dehydrator fan adopts energy-saving high-efficiency low-noise fan. Condensed water is discharged automatically by the steam trap. The energy-saving effect is good. The material tank is made of high-quality imported stainless steel, and the product fully meets the food hygiene standards.

Superheated solvent steam fluidized bed dryer consists of heater, condenser, coarse filter, fine filter, cyclone separator, bag-type secondary dust collector, solvent recovery filter and other components. When the wet material that needs to be dried is pumped into the surface of the boiling carrier, a wet material film is formed, and the heat is carried by the hot air and the carrier. The water molecules are rapidly evaporated, and then dried and then broken by the carrier to break into a powdery product output. The dryer is the first closed loop technology using solvent superheated steam as the heating medium in the inert particle fluidized bed. It integrates drying and solvent recovery, and solves the problem of drying and solvent recovery of alcohol-soluble materials that are difficult to overcome in the contemporary drying technology field. Question. Can be widely used in food, fine chemicals, pharmaceuticals and other industries viscosity continuous drying of dry materials and organic solvent recovery, many users use to prove that high drying strength, economic and social benefits significantly.

Vacuum freeze-drying equipment is suitable for dehydrated vegetables, royal jelly, ginseng and other effects are significant, and has been mass production. In the application process, the device has many advantages: heating the entire material in a radiation manner, heating evenly and without dead angle; the drying speed is 2-3 times faster than the conventional method, shortens the time for heating the material, improves the production efficiency, and can save Resources; drying temperature is low, controlled between -20 °C to room temperature. The dried material can well preserve the nutrients and functional components in the material, and is applicable to the heat-sensitive materials, health products, fruit and vegetable products, Chinese herbs, plasma products and other low-temperature drying products. Vacuum freeze-drying equipment, excellent performance, can make the moisture in the food in the slurry and vacuum conditions, the direct sublimation from the solid and dry without liquid evaporation. It can preserve the original color, smell, taste and shape of foods to the utmost extent. The original nutrients and active substances are rarely destroyed, and the rehydration is rapid. It is no longer necessary to use preservatives. After drying, the products are popular in international markets. Food vacuum lyophilizer Energy-saving food vacuum lyophilizer mainly consists of a quick-freezing warehouse for material freezing, a drying warehouse for sublimation and dehydration, and auxiliary systems such as refrigeration, vacuum and heating. The core equipment is a drying warehouse, and the structure is suitable for the requirements of sublimation and dehydration of frozen materials. The freeze-dried food produced is better than the freeze-dried foods produced by other methods. It is nutritious and its shape, color and taste are basically the same as fresh products. Rehydration is good. Can be widely used in fruits, meat, aquatic products, milk, soy milk, juice and instant noodles, soup, powder vegetables, granular vegetables and other food freeze-dried.

Series of new-type drum dryer drum dryer is a kind of internal heating conduction type rotary drying equipment. The wet material transfers the heat in a heat-conducting manner outside the rolling to reach the required moisture content. The heat is transmitted from the inner wall of the cylinder to the outer wall of the cylinder and then worn. Through the film, thermal efficiency up to 80% -90%, the material drying cycle is short, only 10-15 hours, continuous operation. Widely used in the drying of liquids, ribbons, pastes and viscous materials, such as meat products, dairy products, nutritional cereals, yeast, starch and so on. Roller Scraper Dryer Scraper Puller Dryer. The equipment allows liquid or slurry materials to form a thin film on the heated rolling surface of water vapor or other carrier. The drying process is completed when the drum rotates one circle. After the drying product is automatically scraped with a scraper, the surface of the drum is contacted with the wet material to form a film for drying.

Closed loop belt dryer closed loop belt dryer. The product adopts multi-layer movable stainless steel mesh belts for stacking materials. The hot gas flow passes through the mesh belt and the above materials from bottom to top. The heat exchange is even and full, the speed is fast, and the evaporation intensity is high. It meets the GMP requirements and is suitable for good air permeability. The sheet-like, strip-shaped, granular, and cake-like pasty materials are dried, and are particularly suitable for drying materials that have a high moisture content and do not have a high drying temperature. There are also five-layer belt dryers in China that have the same effects and applicability as described above. High-speed mixing granulator dryer Jiangsu one-step drying equipment Co., Ltd. develops and produces HLG high-speed mixing granulating dryer, which integrates rapid mixing and granulation drying. The entire operation was carried out in the same sealed container. There was no dead angle, and the cleaning was complete and rapid. It complied with GMP specifications. The special feeding system can measure the dry powder and binder and send it to the granulation container. The special fluidized bed structure can reliably sieve powder, continuously discharge dry particles and return fine powder. The product has finished the history that the production of drying equipment in China can only be a single granulation or drying. Compared with the traditional process, the granulation process saves 25% of the binder, and the granulation time is 4-5 times faster. It only takes 7-10 minutes to dry. The time is greatly reduced and it can completely replace the original mixed granulation and fluidized bed drying equipment. It is suitable for wet granulation and drying of tablets, capsules, granules for food, medicine and other industries. Multi-functional coating dryer is a multi-functional equipment that integrates granulation, coating and drying. The use of a special structure of the drive plate, the spiral hot air flow generated particles to form multi-dimensional movements, with a large levitation force, uniform coating, the grain, powder, pills, tablets can be coated characteristics, high quality coating drying, The drying time is short, and it operates in a closed state, reducing dust flying, stable performance and easy operation. The application confirmed that the product meets the requirements of the company's standards. The dryer is widely used in food, medicine, chemical industry and other industries to dry granulation.

The mobile grain dryer uses crop straw gas as heat source, and the drying cost is low. The dry structure is a multi-bin combination, and each bin can be independently cycled and dried, which can effectively solve the problem of easy mildew and germination of grain in China's grain-producing areas. The microwave fixing machine for microwaves uses microwave technology to replace the traditional heat conduction heating and fixing methods. It has a short fixation time and even heating, and can ensure that the tea leaves are naturally stretched and beautiful in appearance. The water content of the produced green tea is reduced, and the tea functional ingredients such as tea polyphenols, amino acids and vitamins increase. The color is more green and the aroma is more pleasant, which improves the quality of the tea.
