1, species selection. In general, the late-maturing varieties are more resistant to storage than the early-maturing varieties, and the dual-purpose varieties have better storage-resistance than fresh varieties, and the anti-crack fruit varieties are more resistant to storage, while the large-fruit varieties are not resistant to storage. To achieve high added value after preservation, we must choose high-quality, storage-resistant varieties. At present, the main varieties of fresh dates are winter jujube, jujube, and jujube. Winter date, snow date is a late-maturing variety, more resistant to storage, Lizao early maturing varieties, intolerant storage. The jujube and jujube dates are generally of the same quality, while the jujube is one of the best varieties of fresh food. 2, harvest time. Harvest time is also an important factor affecting the storage effect. Under normal circumstances, the lower the maturity, the better the good storage performance, and the higher the maturity, the more difficult it is to store. Lizao jujube harvesting effect is good in the white mature stage, and large white dates are required to be harvested in the later stage of white ripening or when the fruit surface is 1/3 red to semi-red. Jin jujube is harvested from half red to three quarter red, and winter jujube is at 1 /3 color harvesting. 3, drug treatment. During the fresh-keeping storage of fresh jujube, a large amount of calcium pectate in the pulp is an important reason for the softening of the fruit. To maintain the hardness of jujube fruit generally treated with calcium, spray cloth and impregnated two methods: Spraying method is 10 days before fruit picking to half a month, to the whole tree sprayed with 0.2% calcium chloride; impregnation method is in the fruit picking After dipping with 0.2% calcium chloride solution for 8-12 hours. In order to kill microorganisms on the fruit surface and prevent or suppress the reinfection of germs, sterilization (disinfection) must be performed. Commonly used disinfectants include thiophanate-methyl, carbendazim and sulfur. There are fumigation methods, spray methods, etc. 4, storage conditions. 1Temperature: After the harvest of jujube fruit, above the freezing point, the higher the ambient temperature is, the stronger the respiration is, the shorter the service life is; otherwise, the lower the temperature is, the longer the service life is. However, when the temperature reaches or falls below the freezing point of the jujube fruit, freezing injury occurs. Therefore, the lower the ambient temperature above the freezing point, the longer the shelf life and the better the effect. According to the determination, jujube fruit freezing point in the range of -2.4 °C - -5.9 °C, in the specific preservation of storage, the general environment should be controlled at 0 °C -1 °C. 2 Temperature: Storage environment temperature requirements reach 90% - 95%. 3 Gas composition: According to the experiment, when the air-conditioned storage is used, satisfying the oxygen concentration of 3%—5% and the carbon dioxide concentration of 3%—4% can significantly improve the storage effect.
The Piglet Feeder is our Honde brand of high quality piglet rearing equipment made from high quality stainless steel SST 304 with automatic welding technology which is one of the advantages of the piglet feeder. The piglet feeder is medium in depth, which prevents it from containing too much food, but avoids the waste of piglets eating food. The piglet feeder is large enough to allow several piglets to be used at the same time, which is very handy. the piglet feeder can hold water or wet food, and will not rust, is conducive to the health of piglets. The piglet feeder's edge is smooth and will not harm piglets that use it. the piglet feeder makes it easy to feed piglets and piglets will enjoy using our piglet feeders.
