Q&A on the use of microwave vacuum dryer for powder
The answers to several questions about flour vacuum dryer are as follows
1. Is the whole equipment electrically driven?
The equipment only consumes electricity and a small amount of cooling circulating water.
2. What is the maximum dry flour capacity? Is the drying time of 1T and 5T the same? If so, how long will it take? If not, how long will it take;
The maximum drying capacity is about 2 tons for a single machine. The drying time is determined by the power of the equipment. For 60kw equipment, 1 ton of material is fed at a time, and the drying time is about 2 hours.
3. When the equipment is dry, in addition to removing moisture, will there be any powder loss to the product itself;
Dry flour basically removes the water in the flour. According to the previous findings of dry food raw materials, it also removes some agricultural residues and volatile organic substances. Even for flour with low moisture content, the storage time at normal temperature can be increased by more than 3 times. It can also prevent flour deterioration.
4. Where does the microwave equipment need to be maintained? Approximate life?
The equipment has been used for more than 6 years by many different customers in the early stage. Only the magnetron must be replaced regularly, with a replacement period of about 10000-12000 hours.
5. Is there any harm to human body? Whether the hazard has been detected by the corresponding national department;
The microwave vacuum dryer belongs to the negative pressure drying equipment. The equipment itself has good sealing performance and will not have electromagnetic leakage. Even the trace amount is within the scope of the national standard. As long as it is not human factors, it will not cause any harm. The national standard is GB/T 5959.6
6. Is the power consumption for evaporation of 1T water 10KW?
The power consumption for evaporation of one ton of water is 1100-1200 kilowatt-hours. It is slightly higher in summer and lower in winter.
7. What is the principle of vacuum? What is the vacuum?
Vacuum drying is based on the principle that the boiling point of water is reduced under low pressure. The vacuum degree of normal operation of the equipment is generally between -0.097-0.0995.
8. What is the specific microwave frequency band and frequency sent by the microwave generator?
The microwave generator frequency is between 2.45-2.46GHz, which is close to the frequency of Bluetooth or WiFi.
9. What is the floor area of 1T and 5T equipment? How long does it take?
At present, only 1T and 2T have standard models. If it needs to be larger, it needs to be customized. 1T covers an area of 5.0 * 2.5 * 2.5 meters. 2T covers an area of 8.0 * 2.5 * 2.5 meters. The time to run once is 2 hours per batch.
