The harvesting and preservation of Dutch beans
First, the harvesting standards of the Dutch beans should be based on the characteristics of the varieties and the needs of consumers. Before harvesting, field management should be strengthened, especially watering should be done so as to avoid a decrease in the rate of defective soybean meal products due to water shortage. Harvesting should take place before sunrise, when the temperature of the soybean meal is the lowest and the moisture content is high. Gently remove the pods and place them in the arbour or in the room. Cover them with wet towels or wet sacks to avoid loss of moisture. After harvesting, they are transported to the processing plant for pre-cooling and other treatments as soon as possible. Second, the pre-cooling of the best cold water, the use of special water pre-cooling equipment, pre-cooling speed, good effect. If there is no special pre-cooling equipment, a simple water pre-cooling method can be used: put the container filled with clean tap water in a 0 °C cold storage for 20 hours, when the water temperature reaches 1 °C, the Dutch beans shipped from the field into the water, Constantly add crushed ice to the water, keep the water temperature at 1°C, and allow the temperature of the Dutch beans to reach 2°C as soon as possible. If you use several containers for continuous operation, it is faster. It can also be used simple forced ventilation pre-cooling method: Distribute the crates or baskets in the cold store, quickly remove the heat by strong cold air, so that the product temperature quickly drops below 2 °C. It is best to spray a little clear water into the basket to prevent wilting. This Law requires a short time and is held in 4 to 6 hours. Packing should be used around the carton or plastic basket with holes to facilitate the entry of cold air and heat dissipation. It is forbidden to use plastic bags, cloth bags and sacks. 10 kg per box (basket) is appropriate. Third, the selection process should be carried out in a low-temperature environment, according to the listing criteria, and pick out pests, diseases and defects, to avoid causing mechanical injury. Fourth, packaging immediately after the completion of packaging, if you can not immediately shipped outside should also be pre-packaged with plastic film or plastic bags. Do not seal the bag mouth to avoid excessive damage caused by carbon dioxide. Export packaging should use waterproof cardboard boxes or plastic boxes. It is best to use plastic foam boxes. The interior of plastic boxes needs thinner packaging paper or film as the inner package, which is moisturizing and heat preservation. Packing boxes should be placed in a cold room before cooling. In order to maintain the low-temperature environment in transportation, it is necessary to add ice in the packing box, and the amount of ice added accounts for 1/5 of the total weight of the goods. The crushed ice is packed in polyethylene film with a thickness of 0.05 mm or more. The bag is sealed and water leakage is strictly prohibited. The ice bag is placed in the middle of the product and ice is best served before departure. V. Storage Waiting for short-term storage for external transportation requires a temperature of 0°C and a relative humidity of 95%. 6. Transportation should be conducted at a low temperature. When using a refrigerated truck or a refrigerated container, the temperature should be lowered to 0°C before loading. The loading and unloading should be as fast as possible.
