Abstract
Description
Technical Field
[0001] This utility model relates to the field of liquor processing technology, and in particular to a heat-insulating pot cover for liquor processing. Background Technology
[0002] Temperature control is crucial in the processing of baijiu (Chinese liquor), especially in stages such as cooking, fermentation, and distillation. For example, during cooking, raw materials like sorghum need to be heated to a certain temperature to gelatinize the starch, preparing for subsequent fermentation. During fermentation, a suitable temperature must be maintained to facilitate the growth and metabolism of microorganisms. In the distillation stage, the heating temperature must be controlled to ensure the smooth distillation of alcohol and other components. Insulating pot covers play a vital role in maintaining temperature stability during these stages, reducing heat loss, and ensuring smooth processing. Existing baijiu processing pot covers are mostly simple in structure and have limited function, while baijiu processing equipment comes in various specifications and models with different inner diameters. Traditional pot covers are usually of fixed size, making it difficult to adapt to equipment with different inner diameters. In practical use, if the pot cover does not match the inner diameter of the equipment, either the pot cover cannot fit tightly against the inner wall of the equipment, resulting in poor sealing and insulation; or the pot cover is too large to install properly, limiting its versatility and applicability.
[0003] During the processing of baijiu (Chinese liquor), especially in stages involving stirring, shaking, or the inflow and outflow of materials, the pot cover is easily subjected to external impacts or vibrations. Existing pot covers mostly rely on simple clips or bolts for fixation, which is not secure enough and can easily loosen, shift, or even fall off during processing. If the pot cover detaches, it not only interrupts production and disrupts its continuity, but can also lead to significant heat loss and even safety accidents, causing losses to the company.
[0004] During the processing of baijiu (Chinese liquor), the steam generated inside the pot condenses into water when it encounters the relatively cool inner wall of the pot cover. Existing pot covers lack effective devices for collecting and removing this condensate, which drips back into the baijiu. For baijiu during fermentation, the incorporation of condensate can alter the composition and acidity of the fermentation liquid, affecting the fermentation process. During distillation, the dripping condensate dilutes the raw liquor, reducing its alcohol concentration and consequently affecting its taste and quality. Therefore, this invention aims to provide a heat-insulating pot cover for baijiu processing that solves the aforementioned problems.
[0005] Furthermore, on the one hand, there are differences in understanding among those skilled in the art; on the other hand, the applicant studied a large number of documents and patents when making this utility model, but due to space limitations, not all details and contents were listed in detail. However, this does not mean that this utility model does not have the features of these prior art. On the contrary, this utility model has all the features of the prior art, and the applicant reserves the right to add relevant prior art to the background art. Utility Model Content

Detailed Implementation
[0022] The following is a detailed explanation with reference to the accompanying drawings.
[0023] Example 1
[0024] This utility model provides a heat-insulating pot cover for baijiu processing, such as... Figure 1 and Figure 2As shown, the device includes a pot cover body 100. A fixing assembly 200 for securing the inner wall of the liquor processing device is provided inside the pot cover body 100. The fixing assembly 200 includes a limiting member 201 fixedly connected to the vertical end of the inner wall of the pot cover body 100, a fixing block 202 for abutting against the inner wall of the liquor processing device, and a rotating disk 203. Several fixing blocks 202 are disposed at the vertical end of the rotating disk 203 and are arranged to extend and retract as the rotating disk 203 rotates. This device, while processing and maintaining the temperature of the liquor, can lock the pot cover through the fixing assembly 200, thereby improving the heat preservation effect and preventing water vapor from leaking out of the pot cover. Therefore, the pot cover of this invention can be applied to liquor processing devices with different inner diameters. By tightly fitting and locking the inner wall, the heat preservation performance of the pot cover is enhanced, and the pot cover is prevented from detaching.
[0025] According to a preferred embodiment, a spiral member 204 is provided on the rotating disk 203. A plurality of fixing blocks 202 have spiral grooves 205 corresponding to the spiral member 204 at their vertically downward ends. The spiral grooves 205 engage with the spiral member 204 to push the fixing blocks 202 into place when the rotating disk 203 rotates in the same spiral direction as the spiral member 204. Figure 3 and Figure 4 As shown, when the rotating disk 203 rotates in the opposite helical direction to the screw 204, it pushes several fixed blocks 202 to extend. The screw 204 can extend along the Archimedean spiral.
[0026] It should be noted that the fit between the spiral component 204 and the spiral groove 205 in this application is a flexible fit. Due to the special characteristics of the Archimedean spiral, its arc length is not perfectly consistent throughout. Therefore, mismatch may occur between the spiral component 204 and the spiral groove 205 (although this error can be ignored in most existing mechanisms). To address this, the spiral component 204 in this application uses a material with flexible edges (i.e., its edges can deform slightly), allowing it to slightly deform to conform to the shape of the spiral groove 205, enabling the spiral groove 205 to rotate from the inside to the outside of the spiral component 204. More preferably, the size of the spiral groove 205 is slightly larger than the size of the spiral component 204, making it more consistent with the special characteristics of the Archimedean spiral. Thus, since the direction of the fixing block 202 against the inner wall of the liquor processing device is radial, even if the size of the spiral groove 205 is slightly larger than the size of the spiral component 204, there will be no wobbling. At the same time, this arrangement solves the problem of mismatch between the Archimedean spiral component 204 and the spiral groove 205.
[0027] According to a preferred embodiment, the helical member 204 is configured as a protrusion extending vertically from the upper surface of the rotating disk 203. The cross-section of the helical member 204 is configured as semi-circular or rectangular. To solve the problem of mismatch between the helical member 204 and the helical groove 205 in the aforementioned Archimedean spiral shape, the cross-sections of the helical member 204 and the helical groove 205 are preferably rectangular (semi-circular in the figures of this application, but this does not mean that a rectangular cross-section cannot be used), and the cross-section of the helical groove 205 is larger than the cross-section of the helical member 204. More preferably, the length of the cross-section of the helical groove 205 along the radial direction of the rotating disk 203 is greater than the length of the cross-section of the helical member 204 along the radial direction of the rotating disk 203. Thus, the fixing block 202 can extend or retract as the helical member 204 rotates.
[0028] According to a preferred embodiment, a rotating shaft 206 is disposed at the axial center of the rotating disk 203. The rotating shaft 206 is fixedly connected to the rotating disk 203. The spiral member 204 extends to the rotating shaft 206. The rotation of the rotating shaft 206 can drive the rotating disk 203 to rotate, thereby causing the spiral member 204 to rotate accordingly.
[0029] According to a preferred embodiment, the limiting member 201 is disposed at the vertical end of the rotating disk 203 and the fixing block 202 in a manner that does not contact the screw member 204. The limiting member 201 has a hole at its axial center for accommodating the rotating shaft 206. The limiting member 201 is directly fixedly connected to the vertical end of the inner wall of the pot cover body 100, thus preventing it from rotating with the rotating disk 203, thereby limiting the fixing block 202.
[0030] According to a preferred embodiment, the limiting member 201 is provided with a plurality of limiting grooves 207 for accommodating the fixing member 202. The limiting grooves 207 extend radially along the rotating disk 203. The fixing member 202 is limited in the limiting grooves 207 and can only move radially along the limiting grooves 207, so that the fixing member 202 can extend into or out of the limiting grooves 207 during the rotation of the rotating disk 203.
[0031] According to a preferred embodiment, a drive mechanism 101 fixedly connected to a rotating shaft 206 is provided at the vertical end of the pot cover body 100. The drive mechanism 101 is rotatably connected to the pot cover body 100, and a sealing seat 102 is provided between the drive mechanism 101 and the pot cover body 100. The drive mechanism 101 can be a knob at the vertical end of the pot cover body 100. More preferably, the drive mechanism 101 can also be a drive motor. The drive mechanism 101 can have a self-locking function, so that the fixing block 202 will not retract due to pressure or residual force after the operator rotates it to a certain angle. Specifically, for example, the drive mechanism 101 can be configured as a self-locking threaded structure. The drive mechanism 101 can also be configured as a servo motor with an electromagnetic brake or a motor with a self-locking function (conical rotor motor), etc. The fixed seat 102 is a sealing seat that can adopt various rotary joint sealing methods (such as planar mechanical seal, spherical concave-convex tight fit seal or line seal, etc.). It is used to prevent the pot cover body 100 from leaking air and to avoid the pressure imbalance inside the pot cover body 100 caused by the rotational connection between the drive mechanism 101 and the pot cover body 100.
[0032] According to a preferred embodiment, a water collecting layer 208 is provided at the vertically downward end of the rotating disk 203. The water collecting layer 208 is arranged inclined axially toward the rotating disk 203. A water collecting element 209 extending axially along the water collecting layer 208 is provided at the center of the water collecting layer 208, and the water collecting element 209 is hollow. The water collecting layer 208 can be made of sponge. The water collecting layer 208 can collect rising water vapor inside the liquor processing device. More preferably, the water collecting layer 208 can be configured as a conical structure, so that after the water collecting layer 208 collects sufficient water vapor, the condensed water gathers toward the tip of the conical structure. The water collecting element 209 is located at the tip of the water collecting layer 208, thereby collecting water flowing out of the water collecting layer 208. Thus, this invention can collect rising water inside the liquor processing device, preventing water from falling into the liquor and affecting its flavor, and improving the taste of the liquor after processing.
[0033] According to a preferred embodiment, a sealing layer 103 for sealing the liquor processing apparatus is provided on the inner wall of the pot cover body 100. The sealing layer 103 extends circumferentially along the pot cover body 100 to form an annular band. A groove 104 for conforming to the liquor processing apparatus is provided at the vertically downward end of the sealing layer 103. The sealing layer 103 can be made of a flexible material. The sealing layer 103 is used to contact the edge of the liquor processing apparatus. The groove 104 is provided on the sealing layer 103 for placing the edge of the liquor processing apparatus. Thus, the device of this invention effectively increases the heat preservation performance of the pot cover.
[0034] According to a preferred embodiment, the inner wall of the pot cover 100 is provided with a threaded groove 105 circumferentially for cooperating with the liquor processing device. This threaded groove 105 is used for connection with the liquor processing device. It should be noted that the pot cover 100 can also be provided with other components for cooperating with and connecting to the liquor processing device, such as magnetic connections, snap-fit connections, bolt connections, etc. This utility model does not limit this; only one feasible solution is provided.
