Description

Technical Field

[0002] On the one hand, tussah silkworm cocoons and pupae are a nutritious food ingredient. The colors of cocoons and pupae are mainly divided into yellow and black. Some studies have shown that the nutritional content and taste of yellow cocoons and pupae are better than those of black cocoons and pupae. Therefore, the market recognition of yellow cocoons and pupae is higher than that of black cocoons and pupae.

[0003] Research has found that the difference in color between yellow cocoon pupae and black cocoon pupae mainly depends on the temperature of the tussah silkworm during the metamorphosis process from silkworm to cocoon pupa after making cocoons. Generally, when the temperature is relatively high, the formation rate of yellow cocoon pupae increases significantly.

[0004] Therefore, at present, breeders will artificially intervene in the temperature of the tussah silkworms during the metamorphosis process after cocooning. The main method adopted is to heat and evaporate water through gas combustion, thereby indirectly increasing the temperature in the cocoon storage room. However, there are problems such as low efficiency and inaccurate temperature control. Moreover, the temperature of the upper part of the same room is different from the temperature on the ground. The temperature of the upper space is higher than that of the lower space, and it is impossible to ensure the temperature balance between the upper and lower parts of the cocoon storage room.

One is to circulate the indoor air, mainly to allow the air in the upper space of the cocoon storage room to circulate and exchange with the air in the lower space. Usually in a fixed space, the heat will move to the upper part of the space, resulting in the temperature of the upper part of the space being higher than the temperature of the lower part of the space, resulting in uneven temperature in the same space. After the air flows, the upper air and the lower air can be heat balanced; the second is to discharge the air in the cocoon storage room to the outside, realize the gas exchange between the indoor and outdoor, and improve the air quality in the cocoon storage room.

When storing silk cocoons, they are generally placed in breathable container boxes. Multiple container boxes are stacked.

If the temperature in the cocoon storage chamber is too high or the humidity is high, or the air quality is poor, the air in the cocoon storage chamber can be discharged to the outside through the external circulation part 420 to improve the problem. When the second fan 422 is running, the air in the cocoon storage chamber enters into the box body 3 through the air inlet 310 of the box body 3 , and then is discharged to the outside through the second cylinder 421 and the telescopic hose 423 under the action of the second fan 422 .

The air is blown by the fan and then flows through the electric heater and is input into the cocoon storage room to heat the air in the cocoon storage room. This embodiment discloses a specific structure of a heating device, but the present application is not limited to the structure disclosed in this embodiment. The air enters the box body 3 from the air inlet 310. Under the action of the fan, the air flows toward the electric heater of the heating device.

In addition, the appropriate humidity is also beneficial to the hatching and metamorphosis of the cocoon pupa. Among them, the humidity sensor 207 can be provided with an interface separately on the box body 3, or it can be connected by threading at the air inlet 310 or other places.

[0043] The tussah cocoon heating equipment of the present application is mainly applicable to two stages in the tussah cocoon breeding process. The first stage is the application in the process of silkworm transformation into cocoon pupa after the tussah silkworm makes cocoons. Studies have shown that tussah silkworm pupae are mainly divided into two types: yellow and black, and the formation of yellow silkworm pupae and black silkworm pupae is mainly related to the temperature during the transformation from silkworm to cocoon pupa, and yellow silkworm pupae are more popular with market consumers. Tussah silkworms generally complete the transformation from silkworm to cocoon pupa about 4 days after cocoon making. Therefore, it is necessary to control the storage temperature of tussah silkworm cocoons during the period from cocoon making to transformation into cocoon pupa in order to increase the formation rate of yellow cocoon pupa. The application of the heating equipment of this application at this stage is generally to start heating when the temperature of the cocoon storage room is lower than 26°C, and to control the temperature between 28-29°C as the optimal temperature, and then stop heating. At this time, the inner circulation part 410 of the gas circulation device is turned on to circulate the indoor air; when the temperature is higher than 30°C, the outer circulation part 420 is started to discharge the indoor high-temperature air to the outside to prevent the temperature from being too high. The humidity index is mainly controlled between 75% and 85%. The humidity referred to in this application is relative humidity. When the humidity is less than 75%, the humidifier is operated to humidify the cocoon storage room. When the humidity is greater than 85%, the humidification operation is stopped.

[0044] The second stage is the process of cocoon incubation, the process of transformation from cocoon pupa to silkworm moth. In the north, the best incubation temperature is generally 25-28℃, but the temperature may be slightly different depending on the environmental conditions in the south and north. The specific temperature value can be set according to local conditions. The humidity is generally controlled at 75%-85%. The heating and humidification process is the same as that of the first stage.
