SO2 gas preservation device for storage and transportation of grapes

Abstract

The invention relates to a SO2 gas preservation device for storage and transportation of grapes. Two anti-corrosion plastic pipelines are connected between a grape container and the device, a gas outlet hole and a gas inlet hole of a storage container are respectively connected with a gas inlet hole and a gas outlet hole of a booster fan, the pipelines are further connected with a SO2 liquid storage tank and a humidifier, a gas concentration detection system and a humidity detection system are arranged at a gas inlet pipeline. The device consists of the booster fan, the SO2 liquid storage tank, a closed thermal insulation pipeline, the air humidifier, a storage environmental SO2 concentration detection instrument, a relative humidity detection instrument and an electrical control cabinet. The concentration and the relative humidity of SO2 in the storage container are controlled by a monitoring system of the SO2 concentration and relative humidity detection instruments, and the system is a whole system which runs automatically; and the pipelines and the storage container are integrated, the sealing property is high, the operation is convenient, the device is inexpensive and the preservation cost is low. As the device strictly detects and controls the gas concentration, the relative humidity and other environmental factors in the storage container, the quality of the grapes during storage and transportation is ensured.

AI Technical Summary

Benefits of technology

This technology helps keep many types of grapes stored safely during shipment without losing their taste or smell due to excessive exposure to harmful chemicals such as sulfur dioxide (SO2) gas that may be present inside them when they were harvested from open-air weather conditions for sale at retail stores.

Problems solved by technology

This patented method described by this patents has technical problem addressed: it cannot be controlled well enough or kept at consistency due to differences between the gas compositions used during storing fruits such as cherries, strawberries, apples, peaches, pears, berry seeds, citrus pulp, tomatoes, melons, breadfires, cranberry leaves, wines, oyster shellfish, seafood products like fish rods, shrimps, tuna, saffron crockery, leather goods, vegetables, nuts, chocolate pieces, spices, detergies, sugarcane roots, tea tree oil, coffee grounds, rice flour, whipped cream, milk powder, cheese mixings, condiments made from these materials, alcoholic drink ingredients containing sulfur dioxide, nitrogen oxides, hydrochlorothiazine, ammonium salicylic acid, calcium salt, magnesium salt, iron salt, manganese ion, copper, selenium, chromate, vanadyl acetoxyde, peracetic acid solution, polysaccharides, proteins, carbohydrates, flavors, antioxiants, pharmaceuticals, pesticids, mineral water, chemical reagents, medications, foodstuffs, cosmetic agents, fertilizers, surfactant solutions, cleanliness regulations, environmental concerns associated therewith, among others.
