Easy Spinach cold storage there are two ways: one is no duct, and the other one is a ventilation channel. (1) No plenum spinach refrigerated law: the house or in the shade range barrier north of shade, and shade was dug several parallel grooves, groove width of 25-30 cm, the same height or slightly shallow depth and spinach, the distance between the grooves is 20 cm. The pre-stored bales of spinach, root down placed upright in the trench, the dry soil sprinkle vegetables and bound in the soil loaded with spinach thickness to cover appropriate. Later with the drop in temperature, graded casing, plain seamless casing to do, play a wind moisturizing effect. Principle is tied vegetables as possible to keep the temperature at a -4 -6 ℃, so the spinach was slightly frozen state. (2) frozen spinach duct method: In the shade or shade range houses impaired north, parallel to the shade material, dig 1-2 meters wide ditch frozen, the same height as the depth of the groove of frozen spinach or slightly lower. In parallel to the ditch and the ditch, and then dug several 25 cm wide, 30 cm deep in the duct, the distance between the air duct between about 25 cm, both ends of the air duct above the ground. In cross-ventilation trail Shujie shop or reed stalk. After pre-cooling the storage of spinach bundles roots down upright on Shujie or reed stalk, there must be an appropriate gap between the food bundles for air circulation and prevent rotting Levin leaf yellowing. After the entire frozen ditch filled with a thin layer of soil cover to wind moisture. After the casing requirements and methods with the above non-plenum of frozen same law. After frozen spinach. It must be thawed prior to listing, to restore fresh state. Thawing method is to dig up the casing, carefully remove the base from the menu bundle of spinach, on temperature: 0-1 ℃ degree environment of very slow thaw. In eels slow the thawing process, the cell gap spinach plant tissue gradually melting ice, is absorbed by the cells, the cells to restore the original state, so the plants can maintain its original fresh state. After about 3-4 days, after completely thawed spinach, the yellow leaves, rotten leaves, remove, rinse with cold water and put on the market in a timely manner. Cold storage method is: the spinach harvest of selected, after renovation, and bind them in weight of about 0.5 kg of small bundles into the post-cold pre-cooled, placed in a polyethylene plastic sack. Loading bundles each containing about 20 dishes. Songzha pocket. Dish rack placed in cold storage, you can put in a plastic dish racks account. In addition to keeping the temperature 0-1 ℃, relative humidity above 95%. Placed in a plastic tent results were better storage, storage 90 days, color, shape, smell, taste change basic elements. Commodity rate of 99%. China Ran refrigeration professional installation of the construction spinach fresh cold storage, cold storage and other vegetables atmosphere.
