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.
New type drum dryer
The CT series drum drying machine developed by Jiangsu Changzhou Huayuan Drying Equipment Co., Ltd. is a kind of internal heating conduction rotary drying equipment. The heat transferred by the heat transfer of the wet material outside the rolling heat reaches the required moisture content, and the heat is transferred from the inner wall of the cylinder. Passed to the outer wall of the tube, and then through the film, the thermal efficiency of 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.
HG roller scraper drying machine
HG Roller Scraper Dryer, developed by Jiangsu One-Step Drying Equipment Co., Ltd. The equipment allows liquid or slurry materials to form a thin film on the heated rolling surface of water vapor or other supports. 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 Jiangsu Changzhou Dajiang Drying Equipment Factory adopts American advanced technology and domestic high-quality raw materials to develop a new type of energy-saving equipment—DWT closed loop belt dryer.
