vacuum dryer technical core
Vacuum dryer is widely used in biochemistry, chemical pharmacy, medical and health, agricultural scientific research, environmental protection and other research and application fields, especially suitable for drying heat sensitive, easy to decompose, easy to oxidize and complex components of materials for rapid and efficient drying. Vacuum dryer mainly uses vacuum drying technology, and realizes continuous feeding and discharging under vacuum state. Due to the low oxygen content in drying under low pressure, it can prevent the drying materials from oxidation deterioration.
Vacuum dryer has the advantages of fast drying speed, high efficiency, and will not damage the nutritional components of the product. It is mainly designed for drying heat sensitive, decomposable and oxidizable substances. At the same time, inert gas can be filled into the interior, especially for materials with complex components, which can be quickly dried. At present, the equipment has been widely used in the dehydration and drying of fruits and vegetables, food, health care products, medicine and so on. Its drying quality is good, and it is more and more favored by users.
The temperature control system of vacuum dryer adopts single-chip microcomputer control technology, temperature control, timing, overtemperature alarm; the display is double screen high brightness digital tube display, the display value is accurate and intuitive, the performance is superior, the touch type button sets the adjustment parameter; the temperature control sensor and other electrical components are all original import parts; it has timing and timing functions; the vacuum dryer can make the studio maintain a certain degree of truth The temperature controller adopts the computer technology to collect and process the temperature signal in the working room, so that the temperature in the working room can be kept at constant temperature automatically. The temperature control system belongs to the p.i.d intelligent temperature control system, with reliable performance and convenient use. The intelligent temperature regulator has the function of over temperature protection. When the temperature in the working room exceeds the set temperature value, the over temperature protection circuit will act and cut off the heating circuit.
The vacuum dryer is composed of a box, a heating plate, a door, a pipe interface and an instrument; the box is made of steel plate, and the box body is equipped with several sandwich heating plates, which are filled with steam, hot water or cooling water; the upper end of the box is equipped with a number of sandwich heating plates, which are filled with steam, hot water or cold water; the upper end of the box is equipped with a vacuum pipe interface to communicate with the vacuum device; and a pressure gauge, a pressure gauge, a pressure gauge, a double layer heating plate are arranged on the top of the box The thermometer and various materials are placed in the drying plate, and then the drying plate is placed on the heating plate in the box. Open the steam extraction valve to make the box reach a certain temperature, and then gradually cool down. After reaching the drying requirements, close the steam valve and air extraction valve, open the inflation valve, open the oven station, and unload the products. When making wheat milk crystal, it needs to go through the process of pumping, heating, drying, foaming, cooling and solidification.
The material contact parts of the vacuum dryer are made of high-quality stainless steel; the reasonable design of material contact parts makes the temperature uniformity of materials receive small change; the inner liner is made of mirror stainless steel; the semicircular four corners are easy to clean; inert gas can be flushed into the interior, especially some items with complex components can be quickly dried.
