YPG series pressure spray dryerThe YPG series pressure-type spray (cooling) dryer uses a pressure atomizer to atomize solution or paste-like materials into fine droplets by means of the pressure from a diaphragm pump. This significantly increases the surface area, allowing for full heat exchange with hot air to achieve rapid drying (drying time ranges from several seconds to几十 seconds). Ultimately, powder or fine granular products are obtained.read more -
ZPG vacuum harrow dryerZPG vacuum harrow dryer is a new type of horizontal batch vacuum drying equipment. Wet materials absorb heat through conduction and evaporate moisture. The scraper agitator continuously removes materials from the heating surface and forms a circulation flow inside the container. After moisture evaporation, it is discharged by the vacuum pump. This machine adopts a large-area jacketed heating method, which has a large heat transfer area and high thermal efficiency. Equipped with a stirring device, it enables the material to form a continuous circulation state inside the cylinder, further improving the heat transfer and mass transfer efficiency of the material.read more -
YZG circular Vacuum OvenCylindrical vacuum dryers heat the material to be dried in a cylindrical chamber and use a vacuum pump to extract air and evaporated water. The drying process takes place under vacuum conditions, significantly accelerating the drying speed of the material. Cylindrical vacuum dryers are suitable for drying materials that require a higher degree of vacuum.read more -
FZG Type Vacuum DryerA vacuum drying oven is a device that dries materials by heating them under vacuum conditions. Square vacuum ovens are used for airtight storage of raw materials. Under the action of a vacuum pump, the square chamber is in a vacuum state, which reduces the boiling point of the raw materials' evaporation and significantly accelerates the drying speed of the materials. Vacuum drying equipment can be divided into static drying and dynamic drying. YZG round and FZG rectangular vacuum drying ovens belong to static vacuum dryers, while SZG double-cone vacuum dryers belong to dynamic vacuum dryers.read more -
SSFD series vacuum freeze dryerFreeze drying is to directly transform the moisture or other organic solvents in the material from a solid state into a gas through sublimation, thereby removing the moisture or other solvents in the material. Freeze drying must be frozen at low temperature and carried out in a vacuum state, so it is also called vacuum freeze drying. Sublimation refers to the process in which a solvent changes directly from a solid state (such as water, like dry ice) to a gaseous state without passing through the liquid state. The product obtained by freeze-drying is called lyophilisate. Traditional drying will cause the material to shrink and destroy cells, while the freeze-dried material structure will not be destroyed and can effectively retain the biological and active integrity of the product.read more -
SSYD series vacuum freeze dryerFreeze-drying is different from other drying methods. It directly converts the moisture or other organic solvents in the material from a solid state into a gas through sublimation, thereby achieving the purpose of removing moisture or other solvents. Freeze-drying must be frozen at low temperatures and carried out in a vacuum state, so it is also called vacuum freeze-drying. Sublimation refers to the process in which a solvent changes directly from a solid state (such as water, like dry ice) to a gaseous state without passing through the liquid state. The product obtained by freeze-drying is called lyophilisate.read more -
SZG double cone rotary vacuum dryerThe double-cone rotary vacuum dryer is an intermittent sealed drying equipment. During operation, the material is added into a closed container, and a heat source (such as hot water, low-pressure steam or heat transfer oil) is introduced into the jacket of the container. Heat is conducted through the tank wall to heat the raw material. Since the container is under vacuum conditions, the reduced operating pressure causes the moisture (solvent) on the surface of the material to reach boiling point and evaporate rapidly. The wet steam is then sucked away by a vacuum pump and recovered.read more -

It is particularly suitable for dehydrated vegetables, traditional Chinese medicine slices, and other materials with high moisture content and temperature requirements; This series of dryers has the advantages of fast drying speed, high evaporation intensity, and good product quality. For dehydrated cake like paste materials, they can also be granulated or made into rod-shaped products...read more -
DW series multi-layer belt dryerDW series multi-layer belt dryer is a mass-produced continuous drying equipment used for drying sheet, strip and granular materials with good air permeability. It is especially suitable for dehydrated vegetables, catalysts, traditional Chinese medicine pieces and other materials with high moisture content and high temperature resistance. This series of dryers has the advantages of fast drying speed, high evaporation intensity, and good product quality. It can also be used for dehydration and drying of pasty materials such as filter cakes after granulation.read more -
DWC series dehydrated vegetable belt dryerThe vegetable dehydration dryer consists of main components such as a feeder, drying bed, heat exchanger, and dehumidification fan. When the dryer is working, the cold air is heated by a heat exchanger, and a scientifically reasonable circulation method is used to make the hot air flow through the dried material on the bed surface for uniform heat and mass exchange. The hot air flow in each unit of the machine is circulated by the circulating fan for hot air circulation, and then discharged with low temperature and high humidityread more -
HZG serise rotary drum dryerThe HZG-type rotary dryer has a cylindrical drum structure with a slightly inclined main body, and its rotational speed can be adjusted within a certain range. Wet materials are fed into the drum through a feeder. Under the flipping action of the lifting plates uniformly distributed on the inner cylinder, the materials are evenly distributed and dispersed inside the dryer. They come into full contact with the hot air passing through the drum (in parallel or counterflow), thereby enhancing heat and mass transfer to achieve the drying purpose. The equipment can adopt various types of lifting plates to adapt to the drying requirements of different raw materials.read more -
Closed cycle spray dryerThe closed-circuit spray drying system means that the drying medium circulates in a closed loop throughout the drying system, and uses inert gas instead of air as the drying medium. The inert gas is generally nitrogen. Inert gas can be recycled in the drying system and plays the role of heat transfer, moisture carrying and dehumidification. The drying system is often operated under positive pressure. If the internal pressure drops, the pressure transmitter can automatically control the entry of nitrogen to ensure the balance of the inert gas concentration in the system and control the oxygen content. The closed-circuit spray dryer is particularly suitable for drying materials containing organic solvents, as well as materials containing toxic gases or that are prone to oxidation during the drying process.read more
