Description

Technical Field

[0001] This utility model relates to the field of biological feed fermentation technology, and in particular to a multi-layer temperature control and gas balance device for solid-state fermentation of biological feed. Background Technology

[0002] Solid-state fermentation of bio-feed is a technology that utilizes microorganisms to grow and metabolize on a low-moisture solid substrate, transforming raw materials into nutrient-rich and functionally optimized feed. This technology boasts advantages such as energy conservation and environmental friendliness, strong adaptability to raw materials, and abundant bioactive substances in the products, making it widely used in the feed industry. In actual fermentation processes, multi-layer solid-state fermentation methods are typically employed.

[0003] In the solid-state fermentation process of biological feed, in order to ensure fermentation efficiency, product quality and microbial activity, it is usually necessary to monitor the temperature of the fermentation tower and regulate the gas balance inside the fermentation tower. However, at present, most methods only detect the feed temperature at a certain location inside the fermentation tower, which has a poor effect on the temperature regulation of the feed inside the fermentation tower. At the same time, the traditional method is to use passive exhaust to release carbon dioxide from the fermentation tower, which can easily lead to carbon dioxide accumulation and cause gas imbalance inside the tank. Utility Model Content

[0004] The purpose of this application is to provide a multi-layer temperature control and gas balance device for solid-state fermentation of biological feed, so as to solve the problems of poor temperature control of feed in fermentation tower and easy accumulation of carbon dioxide, which in turn causes gas imbalance in the tank.

[0005] To address the aforementioned technical problems, this application provides a multi-layer temperature control and gas balance device for solid-state fermentation of biological feed, comprising:

[0006] Multiple heating plates and cooling pipes spaced apart from each heating plate are installed in the interlayer of the fermentation tower. The cooling pipes are connected by connecting pipes. A water supply pipe and a drain pipe connected to the cooling pipes are installed on the outside of the fermentation tower. Multiple temperature detection probes are installed on one side of the fermentation tower between the heating plates and the cooling pipes. Multiple gas supply pipes extending into the fermentation tower are installed on the other side of the fermentation tower. The other end of each gas supply pipe is connected to an air compressor through a main gas supply pipe. An exhaust pipe is connected to the top of the fermentation tower. One end of the exhaust pipe is connected to a negative pressure fan. A control cabinet is fixed on the outside of the fermentation tower. A controller is installed in the control cabinet. Each temperature detection probe and each heating plate is electrically connected to the controller.

[0007] As a preferred embodiment, a multi-layer temperature control and gas balance device for solid-state fermentation of biological feed is characterized in that, after the heating plate is installed around the interlayer sidewall of the fermentation tower, gaps are left at both ends, and the connecting pipe is connected to the upper and lower cooling pipes through the gaps.

[0008] As a preferred embodiment, a multi-layer temperature control and gas balance device for solid-state fermentation of biological feed is provided, wherein an electromagnetic control valve electrically connected to the controller is also provided on the exhaust pipe.

[0009] The solution requires detailed explanation of a multi-layer temperature control and gas balance device for solid-state fermentation of biological feed, wherein a display electrically connected to the controller is also installed on the outside of the fermentation tower.

[0010] Further explanation is needed regarding the proposed solution: a multi-layer temperature control and gas balance device for solid-state fermentation of biological feed includes a carbon dioxide concentration detector electrically connected to the controller at the top of the fermentation tower, and the drive motor of the negative pressure fan is electrically connected to the controller.

[0011] Compared with existing technologies, the present invention provides a multi-layer temperature control and gas balance device for solid-state fermentation of biological feed, comprising multiple heating plates disposed within the interlayer of a fermentation tower and cooling pipes spaced apart from each heating plate, wherein the cooling pipes are connected by connecting pipes. A water supply pipe and a drain pipe connected to the cooling pipes are disposed on the outside of the fermentation tower. Multiple temperature detection probes are disposed on one side of the fermentation tower between the heating plates and the cooling pipes.

Multiple branch gas supply pipes extending into the fermentation tower are disposed on the other side of the fermentation tower, and the other end of each branch gas supply pipe is connected to an air compressor via a main gas supply pipe. An exhaust pipe is connected to the top of the fermentation tower. One end of the exhaust pipe is connected to a negative pressure fan. Through the cooperation of the air compressor, the main air supply pipe, and the various branch air supply pipes, air can be introduced into all parts of the fermentation tower. The negative pressure fan and the exhaust pipe can periodically discharge carbon dioxide from the fermentation tower, achieving active exhaust, preventing the accumulation of carbon dioxide in the fermentation tower, and ensuring gas balance in the tower. A control cabinet is fixed on the outside of the fermentation tower. The control cabinet is equipped with a controller. Each temperature detection probe and each heating plate is electrically connected to the controller. The controller can control the heating plates to heat or stop heating based on the temperature measured by each temperature detection probe. At the same time, when the temperature in any part of the tower is detected to be too high, cooling water can be supplied to the cooling pipe through the water supply pipe to achieve rapid cooling and improve the temperature control effect of the feed in the fermentation tower.
