Embodiment 1

[0030] Add the steam-exploded straw material with a humidity of 75% into the reactor barrel 12 through the feeding port 7, spread the material evenly through the distributor 13 and mix evenly, and start the cold mold cultivation after closing the plexiglass window 4. The cold mold experiment requires that the temperature of the material layer be controlled at 35° C. and the humidity 75% to facilitate the cultivation of fly maggots. After the cultivation starts, the thermocouple and the hygrometer 3 display the temperature of 24° C. and the humidity of 75%, respectively. It is necessary to adjust the temperature of the external air inlet 21 through an external heat exchanger. First, 40°C hot air is introduced to heat the material layer, and the air inlet 19 is dispersed into the interior of the reactor to adjust the temperature. After heating for a period of time, the temperature reaches 35°C, and then the insulation static cultivation is started. When the material layer humidit...

Embodiment 2

[0032] Add the steam-exploded straw material with a humidity of 75% into the reactor barrel 12 through the feeding port 7, spread the material evenly through the distributor 13 and mix evenly, and start the cold mold cultivation after closing the plexiglass window 4. The cold mold experiment requires that the temperature of the material layer be controlled at 25° C. and the humidity 75%. After the cultivation starts, the thermocouple and the hygrometer 3 display the temperature of 20° C. and the humidity of 75%, respectively. It is necessary to adjust the temperature of the external air inlet 21 through an external heat exchanger. Firstly, 30°C hot air is introduced to heat the material layer, which is dispersed into the reactor by the air inlet 19 to adjust the temperature and humidity. At 75%, the material bed is humidified by feeding humid air. By implementing the cold model experiment, the temperature and humidity control in the reactor can be quickly realized, and the ex...

Embodiment 3

[0034] Add the steam-exploded straw material with a humidity of 50% into the reactor barrel 12 through the feeding port 7, spread the material evenly through the distributor 13 and mix evenly, and start the cold mold cultivation after closing the plexiglass window 4. The cold mold experiment requires that the temperature of the material layer be controlled at 25° C. and the humidity 75%. After the cultivation starts, the thermocouple and the hygrometer 3 display the temperature of 21° C. and the humidity of 50%, respectively. It is necessary to adjust the temperature of the external air inlet 21 through an external heat exchanger. Firstly, 30°C hot and humidified air is introduced to heat and humidify the material layer, and the air inlet 19 is dispersed into the reactor to adjust the temperature and humidity. After heating and humidifying for a period of time, the humidity first reaches 75%, and then the air is adjusted to enter the drying process. Hot air, the temperature re...

Abstract

The invention relates to an automatic control bioreactor for breeding maggots and earthworms and a solid culture method. By controlling the temperature and humidity of the reactor, the growth of the maggots and the earthworms can be effectively promoted, and the growth period is shortened. Meanwhile, at the maturation period of the maggots and the earthworms, animals are promoted to move to a collector through illumination control and temperature adjustment so as to realize effective separation and reduce separation cost. The bioreactor comprises a reactor bottom, a reactor light transmission window, a reactor top, a charging part, a maggot and earthworm collector, a forced ventilation device, an automatic process controlling device and a heat exchanger. The method of the invention can realize automatic breeding of the maggots and the earthworms, and is applied to scale zooming; and the reactor has the characteristics of simple structure, convenient operation, low operating cost and environmental protection.

Description

technical field [0001] The invention belongs to the technical field of breeding and breeding of fly maggots and earthworms, and in particular relates to an automatic control reactor and a cultivation method for breeding of fly maggots and earthworms. Background technique [0002] With the rapid development of urbanization and the intensification of livestock and poultry breeding, livestock and poultry manure, urban kitchen waste, and urban domestic sludge are piled up in a concentrated manner, far away from farmland, and most of them are not used as organic fertilizers. In addition, the rapid increase in population and the increase in human activities have weakened the self-purification ability of the environment. If these wastes can be processed innocuously and turned into high-quality organic fertilizers, it will not only reduce environmental pollution, but also be very beneficial to the healthy development of agriculture. [0003] Both fly maggots and earthworms can dige...
