Description

Technical Field

[0001] This utility model relates to the field of edible fungi processing technology, and in particular to a high-pressure steam sterilizer. Background Technology

[0002] Edible fungi refer to large, edible mushrooms, commonly known as mushrooms. There are nearly 950 known species of edible fungi in China, most of which belong to the Basidiomycota. Common edible fungi include: shiitake mushrooms, straw mushrooms, button mushrooms, wood ear mushrooms, silver ear mushrooms, monkey head mushrooms, bamboo fungus, matsutake mushrooms, button mushrooms, red mushrooms, Ganoderma lucidum, cordyceps, truffles, white lingzhi mushrooms, and porcini mushrooms. To ensure the safety of edible fungi, they need to be sterilized by high temperature and high pressure during production and processing.

[0003] The existing high-pressure steam sterilizers for edible fungi processing have a simple structure. In actual use, they have low utilization of gas heat energy and consume a lot of gas. Moreover, after the edible fungi are sterilized at high temperature and pressure, they need to stand for a long time to allow the internal temperature and pressure to drop before the sealed lid can be opened and the edible fungi can be poured out. This seriously restricts the sterilization efficiency of edible fungi. Utility Model Content

[0004] This disclosure relates to a high-pressure steam sterilizer, which solves the problem that existing high-pressure steam sterilizers for edible fungi processing require a relatively long period of time to allow the internal temperature and pressure to drop before the sealed lid can be opened and the edible fungi can be poured out, which seriously restricts the sterilization efficiency of edible fungi.

[0005] In a first aspect, this disclosure provides a high-pressure steam sterilizer, specifically comprising: a support frame, a high-pressure resistant pot body, a sealing cover, a crossbar, a screw, a positioning pin, a heat-retaining sleeve, and hydraulic cylinders; the high-pressure resistant pot body is connected to the top of the support frame and is located at the top of the burner head; a sealing cover is fastened to the top of the high-pressure resistant pot body, and a pressure relief valve is provided on the sealing cover; a crossbar is connected to the top of the high-pressure resistant pot body, and a positioning pin is connected to the end of the crossbar, the positioning pin being connected to the top of the high-pressure resistant pot body; a screw is threadedly connected to the center of the crossbar, a handwheel is provided at the top of the screw, and the bottom of the screw is rotatably connected to the sealing cover; a heat-retaining sleeve is connected to the bottom of the high-pressure resistant pot body, and two hydraulic cylinders are connected to the bottom of the support frame.

[0006] Furthermore, the top of the pressure cooker body is provided with an external connecting hole, and the two opposite ends of the crossbar are provided with internal connecting holes. The internal connecting holes are connected to the external connecting holes, and the positioning pin passes through the external connecting holes and the internal connecting holes.

[0007] Furthermore, a heat-conducting strip is arranged around the bottom of the pressure cooker body, and the top of the heat-conducting strip is spirally inclined.

[0008] Furthermore, the heat-concentrating sleeve is fitted onto the outside of the bottom of the pressure-resistant pot body, and the inner side of the heat-concentrating sleeve is welded to the heat-conducting strip.

[0009] Furthermore, the pressure cooker body has a cooling channel arranged in a circular pattern inside, and an inlet and a outlet are provided outside the cooling channel. The inlet and outlet of the cooling channel are connected to the circulating cold water pipeline through a flexible hose.

[0010] Furthermore, the support frame is rotatably connected to the pressure-resistant pot body, and the support frame is symmetrically provided with arc-shaped sliding holes on the outside, and the heat-collecting sleeve is symmetrically provided with sliders on the outside. The sliders are slidably connected in the arc-shaped sliding holes, and the pressure-resistant pot body can rotate at an angle of 0 to 90 degrees.

[0011] Furthermore, the cylinder body of the hydraulic cylinder is rotatably connected to the support frame, and the piston of the hydraulic cylinder is rotatably connected to the slider.

[0012] This utility model provides a high-pressure steam sterilizer, which has the following beneficial effects:

[0013] When this invention is in use, with the crossbar installed on the top of the pressure cooker, the outer connecting hole and the inner connecting hole are connected. The positioning pin is inserted into the outer connecting hole and the inner connecting hole to fix the crossbar. Rotating the screw causes the sealing cover to move downward, making the sealing cover tightly contact the pressure cooker body, effectively ensuring the internal sealing of the pressure cooker body. The heat-conducting strip increases the heating area at the bottom of the pressure cooker body, allowing the edible fungi inside the pressure cooker body to heat up faster. The heat-collecting sleeve guides the rising hot airflow, allowing the hot airflow to circulate between the pressure cooker body and the heat-collecting sleeve. The heat-conducting strip can more fully absorb heat and conduct it to the inside of the pressure cooker body, effectively saving gas energy consumption and thus significantly reducing costs.

[0014] In addition, after the edible fungi inside the pressure cooker are sterilized under high temperature and pressure, cooling water enters the cooling channel to assist in cooling the inside of the pressure cooker. This allows the inside of the pressure cooker to drop to a low temperature and low pressure state in a short time, so that the edible fungi can be poured out, effectively improving the sterilization efficiency of the edible fungi. Once the inside of the pressure cooker is in a low temperature and low pressure state, the sealing cover is opened, and the hydraulic cylinder drives the pressure cooker to rotate, which automatically pours out the edible fungi inside the pressure cooker for the next batch of high temperature and high pressure sterilization, ensuring the sterilization efficiency of the edible fungi.
