Environment-friendly tea leaf purification and residue removal system and application thereof

Abstract

The invention discloses an environment-friendly tea leaf purification and residue removal system and application thereof.The system comprises an ozone sterilization device, a purification and residue removal device, an ozone supply device, an automatic control device and a supporting frame device.The purification and residue removal device is arranged in the ozone sterilization device; the ozone supply device and the automatic control device are arranged outside the ozone sterilization device; the supporting frame device is arranged at the lower end of an ozone sterilization cabin.The system is designed according to the defect that tea leaves contain microorganisms, mould, worm egg impurities, heavy metal and pesticide residues.Based on the technical principle that ozone decomposition and volatilization can be inhibited in a low-temperature controlled airtight or non-airtight device environment and the fact that a low-temperature ozone water solution has the effects of quick pre-cooling, sterilization, purification and residue removal, quick pre-cooling, sterilization, purification and residue removal of the tea leaves are realized.The system has the advantages that harmful substances such as the microorganisms, mould, worm egg impurities, heavy metal and pesticide residues are effectively removed and decomposed, nutrient losses and mould depletion are reduced, quick dehydration is achieved, the structure is simple, and operation is easy.

Description

Technical field: [0001] The present invention relates to a green purification and removal system for green tea leaves and its application, in particular to a system for effectively suppressing the ozone components contained in low-temperature ozone aqueous solution or ozone ice by using a low-temperature airtight environment and adopting manual, semi-automatic or automatic control methods The technical method of decomposition and volatilization; according to the design requirements, a device system developed according to the principles of rapid pre-cooling, sterilization, purification and dehydration of green tea, which can realize the functions of airtight or non-airtight at low temperature. The system is widely used in green tea plants; fruits and vegetables; edible fungi; wild vegetables; aquatic products; lotus root, taro, lotus seeds, lily and wolfberry; fresh corn, fresh soybeans and other grains; plant seeds; walnuts, Dried nuts such as chestnuts, peanuts, pine nuts, ha...

Problems solved by technology

[0011]According to the "freezing point warehouse" storage project developed by the technicians of Liaoning Dongfang Sun Industrial Co., Ltd. and Liaoning Natural Ice Technology Co., Ltd. using the patented technology of ice refrigeration constant temperature preservation system The storage test shows that even if the storage method of airtight ice storage is chosen, the ozone component contained in the ice crystals will be reduced to oxygen in a short period of time and volatilize completely. Therefore, ozone ice has the inherent disadvantage that it cannot be stored for a long time The disadvantage is the technical bottleneck that prevents large-scale and effective application of ozone ice

[0012]At present, due to the concentration of tea harvesting period, processing, fresh-keeping storage and cold chain logistics supporting facilities do not match the layout of the tea industry, more than More than 50% of high-quality green tea cannot be harvested, processed and sold in the market

In addition, in the process of tea harvesting, processing, fresh-keeping storage, cold chain logistics and commodity for sale, due to the lack of and inability to enter the cold storage in time for fresh-keeping storage, oxidative degreasing, mold infection and deterioration, food additives exceeding the standard and product shelf life expired, etc. Factors have caused more than 10% of the domestic annual production and sales of 1.6 million tons of tea to be turned into food waste and lost. This alone, there are more than 160,000 tons of tea resources wasted and lost each year, equivalent to 8 billion yuan.
