The invention discloses a transfer silkworm cocoon separator, which comprises a hopper for putting silkworm cocoons and a passage below the hopper, and is characterized in that the joint of the hopper and the passage is provided with a rotating shaft which is provided with a cocoon-moving tray; one side of the hopper is provided with a cocoon isolating spring leaf of which the lower edge is close to the cocoon-moving tray and keeps certain distance from the cocoon-moving tray; and the other side of the hopper is provided with a cocoon blocking spring leaf of which the lower end enters the passage along the gap of the cocoon-moving tray and is not contacted with the cocoon-moving tray or the passage. The transfer silkworm cocoon separator causes the silkworm cocoons to fall into a groove through the rotation of the cocoon-moving tray, one side of the cocoon-moving tray uses the cocoon isolating spring leaf to prevent a plurality of the silkworm cocoons from falling into the passage simultaneously, while the cocoon blocking spring leaf on the other side can move off the silkworm cocoons which are likely to be adhered to the cocoon-moving tray, thus the silkworm cocoons are separated to fall into the passage one by one and get to appointed detection positions along the passage. The transfer silkworm cocoon separator has the advantages of simple structure, reliable function and small volume without cocoon blocking and blockage, is convenient to be provided with a plurality of passages to work in parallel, and can be widely applied to occasions for separating the silkworm cocoons at a higher speed.

The invention discloses a rolling water-spray cocoon cooking machine comprising a conveyor belt used for conveying cocoon cages, and a housing enclosing the conveyor belt. The housing is provided with an inner cavity capable of accommodating materials. The housing includes a cocoon feed part, a preheating part, a cooking part, a regulating part and a cocoon discharge part sequentially along the conveying direction of the conveyor belt. The cooking part locates at one end of the conveyor belt. A cooking chamber encloses roll shafts at the ends of the conveyor belt. The cooking chamber includes an upper cooking chamber, a middle cooking chamber and a lower cooking chamber according to the end structure of the conveyor belt. The rolling water-spray cocoon cooking machine has the advantages that intra-layer and inter-layer sericin in cocoons can be swelled evenly and cleanliness of raw silk is improved.

A cocoon sorting machine comprises a frame, cocoon sorting platforms, cocoon sorting slots, cocoon sorting slot retaining plates, a near-infrared light source, beam splitters, a receiver, high-pressure air nozzles, an air compressor, collection bags and a controller. By near-infrared spectroscopic analysis for cocoon shell weight detection, quick detection and accurate cocoon sorting are realizedthrough the near-infrared spectroscopic cocoon sorting machine. By adoption of the multiple beam splitters, each cocoon sorting platform can be completely covered by one light source, and accordinglycost saving is realized, and cocoon sorting efficiency is improved.

The invention provides a quick freezing pupa killing method for fresh silkworm cocoons, particularly comprising the following steps that: solid dry ice is taken as a cold source to absorb heat of the fresh silkworm cocoons, and simultaneously carbon dioxide obtained through sublimation of the dry ice is taken as the cold source to blow over the fresh silkworm cocoons and exchange heat with the fresh silkworm cocoons so as to make the temperature of the fresh silkworm cocoons reduced to below a given temperature and maintain for a period of time. The invention simultaneously provides a device for realizing the method, comprising an insulated cabinet body and an endless apron, wherein, a cold source cabinet body is arranged on the upper part of the insulated cabinet body, and the solid dry ice is arranged inside the cabinet body; the bottom of the cold source cabinet body is provided with a heat exchange plate; a cold blast pipe is arranged on the lower side of the endless apron, and anopening of the cold blast pipe faces to the endless apron; the cold blast pipe is communicated with the cold source cabinet body; and a fan is arranged on an inlet end of the cold blast pipe. By adoption of the method and the device, the pupa killing production cycle can be obviously shortened and the labor efficiency can be obviously improved; moreover, because pupae are killed at a low temperature, fresh cocoon shells and pupal cells maintain natural state, thereby the quality of the fresh cocoon shells and the pupal cells is slightly influenced and good-quality raw materials are provided for the silk reeling technique and deep-processing of fresh pupae.

The invention provides a cleaning device for silkworm cocoons. The device comprises a machine body, wherein a power chamber is fixed in the machine body, a power device is fixed in the power chamber,a soaking and filtering chamber is fixed in the inner wall of the lower side of the power chamber, a connecting rod hole is in communication with the portion between the soaking and filtering chamberand the power chamber, so that convenience is provided for the power device to transmit power into the soaking and filtering chamber, and a silkworm cocoon soaking device is fixed in the soaking and filtering chamber. Silkworm cocoons are a raw material of silk quilts and often used in daily life, in order to ensure the high quality of the silkworm cocoons and remove some surface dirt, people generally use a boiling cleaning method, and silkgrowers personally operate the process mostly at present, the operation is cumbersome, and the efficiency is low.
