Embodiment Construction

[0014] Fresh cocoons are packed in baskets → fresh-keeping transportation → freezing treatment → temperature-controlled storage → rebalancing treatment. The steps are:

[0015] 1. Cocoon harvesting and subpackaging: put fresh cocoons harvested or purchased into each basket with about 25 kg of fresh cocoons, about 12000-16000 fresh cocoons, and leave 1-2 cm at the top of the basket to prevent the cocoons in the basket from being damaged. The upper layer is under pressure. Place the fresh cocoons in baskets at 23-27°C and transport them away within 4 hours. About 45 cocoon baskets are needed per ton of fresh cocoons;

[0016] 2. Fresh-keeping transportation: Under normal temperature conditions (22-28°C), the above-mentioned fresh cocoons in baskets are used for fresh-keeping transportation by general trucks. Each car can be stacked in 5 layers, and each layer can hold 12 baskets. The interior of the carriage should be kept ventilated, and strong vibration and sun exposure mus...

Abstract

The method for storing-treatment of the fresh silkworm cocoons incldues such steps as loading fresh silkworm cocoons in baskets, antistaling transporting in air-permeable coach without sunshining, stacking the baskets on the pallet far from ground, and storing in cold storage at -4-10 deg.C. Before the cocoons are used, they are defrozen at ordinary temp., and equilibrium treatment in cool wind. Its advantages are high cocoon quality and high silk output rate.

Description

technical field [0001] The invention relates to the technical field of drying and storage of silkworm cocoons, and more particularly relates to a storage and treatment method for fresh silkworm cocoons. Background technique [0002] Silkworm cocoons are produced in more than 60 countries and regions in the world, and the total annual production of cocoons reaches 670,000 tons. Countries have been using cocoon drying and storage technology to meet the needs of industrialized silk reeling all year round. Even Western Europe, Japan and China, where sericulture technology has always been relatively developed, are still in this circle, and there is no breakthrough. [0003] The current cocoon drying technology mainly uses kang stove and hot air circulation cocoon drying machine to dry cocoons. There are also heat treatment technologies such as far infrared radiation, chimney gas purification heating, natural gas heating, and fuel heating. These convention...
