Description

Technical Field

[0001] The utility model belongs to the technical field of fermentation devices, and in particular relates to a solid feed fermentation device for a laboratory. Background Art

[0002] Fermented feed refers to the process of decomposing macromolecules and anti-nutritional factors in plant substances that are difficult for animals to absorb, such as cellulose, hemicellulose, pectin, lignin, etc., through the growth, development and metabolic activities of microorganisms, to generate or synthesize small molecule active peptides, monosaccharides, various digestive enzymes, amino acids, vitamins, antibacterial substances and other nutrients that are more conducive to animal digestion and absorption, thereby improving the nutritional content of the feed and turning it into a feed with many advantages such as being green, safe and efficient.

[0003] At present, the common methods for industrial production of fermented feed are solid-state fermentation and liquid fermentation. Solid-state fermentation refers to the process of fermentation of single microorganisms or composite microorganisms in plant materials with sufficient relative humidity under the condition of no free water. Solid-state fermentation has the advantages of no need to treat wastewater, low production cost and high output rate due to the low water content of solid matrix raw materials.

[0004] Solid-state fermentation equipment is generally divided into two categories according to the different oxygen consumption requirements of microorganisms: equipment that mainly uses aerobic fermentation. Common aerobic fermentation methods include pile fermentation, tank fermentation, belt fermentation, and ton bag fermentation; equipment that mainly uses anaerobic fermentation. Common anaerobic fermentation methods include breathing bag fermentation and barrel fermentation.

[0005] In the prior art, when performing solid-state fermentation, aerobic fermentation and anaerobic fermentation require different equipment for fermentation. When conducting fermentation experiments in the laboratory, both fermentation methods are often required to be experimented with, resulting in the laboratory requiring two different sets of equipment for fermentation, which is not only costly but also takes up space.

[0006] In view of this, in order to solve the above technical problems, the utility model provides a laboratory solid feed fermentation device which can perform both aerobic fermentation and anaerobic fermentation, does not require replacement of fermentation equipment, is convenient and practical, has low equipment cost, simple structure, and is easy to apply in production. Summary of the invention

[0007] The utility model provides a laboratory solid feed fermentation device, which can perform both aerobic fermentation and anaerobic fermentation, does not need to replace the fermentation equipment, is convenient and practical, has low equipment cost, simple structure, and is easy to apply in production. The specific scheme is as follows:

[0008] A solid feed fermentation device for laboratory use, comprising a tank body with an opening at the top and a tank cover matched with the tank body, the tank cover is inlaid with a first sealing ring, an exhaust hole is vertically opened on the top of the tank cover, a sealing structure that can seal the exhaust hole is provided on the exhaust hole, a handle is provided on the top surface of the tank cover, arc grooves are horizontally opened on opposite sides of the exhaust hole, the sealing structure comprises a sealing block arranged on the exhaust hole, pull rods that can be rotated up and down are respectively provided on opposite sides of the sealing block, spring positioning beads are connected to the opposite sides of the two pull rods away from the sealing block, long strip slide grooves are opened on both side walls of the arc groove along the curvature direction, positioning holes suitable for spring positioning beads are opened on the slide grooves on both sides of the end of the arc groove, and a lifting block is connected to the top surface of the sealing cover.

[0009] Furthermore, a second sealing ring is embedded in the sealing block.

[0010] Furthermore, the outer diameter of the first sealing ring is larger than the inner diameter of the tank body and smaller than the outer diameter of the tank body.

[0011] Furthermore, the tank body is made of glass material with a thickness of 4.5 mm, and the tank cover is made of wood material.

[0012] Furthermore, a plurality of positioning notches are spaced apart on the circumference of the top of the tank body, and a plurality of positioning blocks suitable for the positioning notches are horizontally connected on the circumference of the tank cover.

[0013] The beneficial effects of the utility model are:

[0014] The utility model discloses a solid feed fermentation device for laboratory use. By arranging a sealing ring, an exhaust hole and a sealing structure on a tank cover, a user can, according to actual solid fermentation needs, pull a lifting block to move the sealing block upwards when performing aerobic fermentation. The spring positioning beads arranged at the ends of the two pull rods enter the positioning hole for positioning, so that the exhaust hole is connected with the tank body, thereby meeting the oxygen consumption needs of microorganisms. When performing anaerobic fermentation, the exhaust hole is closed by the sealing block to form an anaerobic environment, so that one device can perform two fermentation methods. The device is convenient and practical, has low equipment cost, simple structure and is easy to apply in production. BRIEF DESCRIPTION OF THE DRAWINGS
