Refrigerant is a very important additive when the fruit and vegetable freeze dryer is running, but the following matters must be paid attention to when using it: ① Before the refrigerant, the quality of the refrigerant must be determined, and the refrigerant can be charged only after the quality is no problem. The poor quality refrigerant is very destructive to the compressor and the refrigeration system, which will affect the operation of the refrigeration system at light level, and damage the compressor at worst. ②If the refrigerant is azeotropic, it is not necessary to t ...

The common faults of the refrigeration system of vacuum freeze dryer mainly include high pressure alarm, compressor motor overload, motor temperature too high, oil pressure difference alarm, water pressure alarm and the actual effect of expansion valve adjustment. Let’s talk about the causes and solutions of these common failures: (1) High pressure alarm: The amount of water in the water condenser is insufficient or the water temperature is too high; some scale is formed inside the water condenser, which reduces the heat conversion efficiency; the low-pressure pipe ruptures ...

The vacuum freeze dryer is based on the ultra-low temperature freezing of the raw materials to be dried, and the solid water in the raw materials is upgraded to a vapor state in the freeze-drying bin of the high vacuum pump, so as to achieve the purpose of drying, and can preserve the taste and taste of food to a certain extent. nutrient. The following will tell you the detailed operation process of the vacuum freeze dryer: 1. Sample placement: 1. Put the pre-processed items in the material tray, and then put the material tray in the freeze-drying rack. 2. Place the tempera ... Read More

Food freeze dryer is the abbreviation of food vacuum freeze dryer. It is a drying equipment that uses the principle of sublimation to remove moisture in food through low temperature freezing and vacuum sublimation processes. At present, my country's economy is developing rapidly, and people's requirements for food are constantly improving, which at the same time brings rapid growth to the demand market for agricultural products and food. With the support of national policies for rural revitalization, the deep processing of agricultural products has also become a "mainstream ... Read More

Share how to use the automatic counting machine and what to pay attention to The working principle of the automatic particle counting machine: when working, pour the medicine particles into the top hopper, and adjust the primary, intermediate and final vibrating feeders appropriately, so that the piled medicine particles in the hopper gradually become continuous along the vibrating groove plate. The strip slides straight down to the blanking port. Then the drop detection channel one by one adopts the principle of photoelectric effect to input the working signal generated by ... Read More

Understand these conditions of the automatic quantitative powder packaging machine, and then start the work The automatic quantitative powder packaging machine adopts microcomputer control and hybrid stepping motor drive technology, which is stable and reliable in work, with high repeatability and low noise. It can work in constant volume or quantitative mode. The blanking is controlled by a photoelectric switch and is not affected by the environment. The part in contact with the material is made of stainless steel, which has strong corrosion resistance and does not pollute ... Read More

The automatic high-speed tablet press is mainly used in pharmaceutical, chemical, food, electronics, metallurgy, daily necessities and other industries. This machine can press various granular raw materials into round tablets, special-shaped tablets, cartoon tablets, double-sided positioning and engraving tablets, two-color tablets, etc. maintenance: 1. Turbine box transmission system Daily check the bottom of the turbine box, the end cover of the worm, and the oil level observation window for oil leakage, oil leakage, and abnormal noise. Theoretically, every 2000 hours or ... Read More

The vacuum freeze-drying machine is mainly dehydrated and freeze-dried in a vacuum closed environment (low temperature and low pressure conditions). Fruits and vegetables are made into ready-to-eat fruits and vegetables through the vacuum freeze-drying process, which not only reduces the spoilage rate of fruits and vegetables to a certain extent, but also retains the nutrients of fruits and vegetables. The ingredients make fruits and vegetables more convenient, healthy and nutritious to eat, and meet the needs of consumption upgrades. Environmental requirements for the inst ... Read More

When the freeze dryer is running, refrigeration is very important, which directly determines the operating efficiency of the equipment, but there are many reasons why the equipment does not cool, so what are the reasons for this? 1. ① The expansion valve is opened too much, at this time, the temperature of the shelf or the water vapor condenser does not drop to the set value, and the compressor is seriously frosted. ②The opening of the expansion valve is too small, and the temperature cannot be lowered at this time, but the temperature of the compressor is very high, and th ...
