Technical Field

[0003] In addition to the traditional straw twisted cage (centipede cage), the "square cage" disclosed in Chinese patent announcement number CN2759172Y has been widely used in the existing cocooning equipment for silkworms. While showing its unique technical performance, this square cage also exposes its shortcomings such as difficulty in picking cocoons due to its structural deficiency. Moreover, since this square cage is generally made of paper, it has poor reusability and is difficult to disinfect and sterilize, which has an obvious negative impact on its normal and effective use.
[0004] Chinese patent CN104145890B discloses a cocooning tool for silkworms, which has three structural forms: a single-layer cocoon sheet, a composite cocoon sheet and a cocoon net, and a composite cocoon sheet and a cocoon sheet. The cocoon sheet and the cocoon net are transparent on all sides, and there are silk hanging columns around the cocoon nests. There are silkworm resting strips in front of each row of cocoon nests. Chinese patent CN208940731U discloses a convenient cocooning tool, including a cocoon net, and supporting side strips are arranged on the four sides of the cocoon net. The cocoon net includes cocoon strips, and the cocoon strips are crossed to form a grid-like cocoon net, and the cocoon net is folded. The cocooning tool adopts a frameless design. Chinese patent 208940730U discloses a rectangular cocooning tool that is easy to use, including a cocoon net and a frame. The cocoon net is arranged in the frame. The cocoon net is formed by the cross-cluster strips to form a grid-like structure. A small support platform and a large support platform are arranged on the top surface of the frame. However, the columns surrounding the cocoon-making room are cylindrical structures, which will leave dents on the cocoons when they are large, affecting the quality. Moreover, its structure is too complicated, resulting in low structural strength, which is not conducive to industrial processing and movement.

Weigh the sample every 10 minutes and record the moisture loss until the sample returns to a constant weight. Plot the moisture retention rate curve and calculate the time required for 50% moisture loss.
