Description

Technical Field

[0001] This utility model belongs to the field of rice wine production technology, specifically relating to a cooling device for rice wine production. Background Technology

[0002] Rice wine, also known as fermented rice wine or sweet wine, was formerly called "Li". Its main ingredient is glutinous rice, hence the name glutinous rice wine. In northern China, it is generally called "rice wine" or "sweet wine". It is a sweet rice wine made by fermenting steamed glutinous rice with yeast (a special type of microbial yeast).

[0003] Rice wine is a sweet rice wine made by fermenting steamed rice grains with yeast. Its brewing process is simple, its taste is sweet and mellow, and its alcohol content is extremely low, making it very popular. my country has a long history of brewing wine using high-quality glutinous rice, dating back over a thousand years. Rice wine has become a daily beverage for farmers. Rice wine production requires first steaming the glutinous rice, then cooling it before mixing it with yeast for fermentation. Therefore, spreading the steamed glutinous rice out to cool on a cooling bed is a crucial step in rice wine production.

[0004] In existing technologies, the raw materials are typically laid out statically during the cooling process of rice wine. Since the raw materials are at a relatively high temperature in the initial cooling stage, if they are not turned over promptly, heat will accumulate inside the materials, prolonging the cooling time, increasing the risk of microbial growth, and making it difficult to accurately control the cooling temperature, thus affecting the subsequent fermentation process. Therefore, we provide a cooling device for rice wine production to solve these problems. Utility Model Content

[0022] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0023] Please see Figure 1 As shown, this utility model embodiment provides a cooling device for rice wine production, specifically including a shell 1. The shell 1 is made entirely of stainless steel, making it sturdy, durable, and easy to clean. Its rectangular shape effectively accommodates various components, facilitating placement in the production workshop. Four support legs 2 are fixedly installed at the bottom of the shell 1. The support legs 2 are cylindrical, made of high-strength carbon steel, and have an anti-rust treatment. They are firmly connected to the shell 1 by welding, providing a stable support foundation for the entire device and ensuring that the cooling effect is not affected by shaking during operation. A cooling drawer 3 is slidably connected to the inner wall of the shell 1. The cooling drawer 3 is made of food-grade plastic, non-toxic, odorless, high-temperature resistant, and corrosion-resistant. Its rectangular shape has fine ventilation holes at the bottom to facilitate air circulation and heat dissipation. The sliding connection with the inner wall of the shell 1 makes the drawer slide smoothly, facilitating the loading and unloading of raw materials. At the same time, it effectively prevents raw material leakage during the cooling process, ensuring the cleanliness and hygiene of the work area. Ventilation windows 4 are installed at both ends of the shell 1. The ventilation windows 4 are rectangular and consist of a metal frame and a fine stainless steel filter. The filter can prevent external impurities from entering the interior of the shell 1 and ensure the cleanliness of the cooling environment. A cooling fan is installed inside the ventilation window 4. The fan blades are made of lightweight and high-strength plastic material and have been optimized in shape to generate efficient and stable airflow, accelerate the air circulation inside the shell 1, and work together with the turning mechanism 6 to promote rapid and uniform heat dissipation of the raw materials.

[0024] Please see Figure 2 and Figure 3As shown, the housing 1 is equipped with an adjustment mechanism 5. The adjustment mechanism 5 includes a motor 501 fixedly installed on the outer surface of the housing 1. The motor 501 is a geared motor with moderate power, which can provide stable torque output. An adjustment screw 502 is fixedly connected to the output end of the motor 501. The adjustment screw 502 is made of high-strength alloy steel, and its surface is finely machined, with good thread precision. It rotates with the housing 1 through a bearing seat, and the rotation process is smooth and stable, reducing energy loss. A movable frame 503 is threadedly connected to the outer surface of the adjustment screw 502. The movable frame 503 is made of aluminum alloy, which is lightweight and high-strength. It can move laterally stably under the guidance of the guide rod 504. Two guide rods 504 are slidably connected to the inner wall of the movable frame 503. The guide rods 504 are also made of high-strength alloy steel, with a smooth and wear-resistant surface. Both ends of the guide rods 504 are fixedly connected to the inner wall of the housing 1 by welding or threaded connection, ensuring that the movable frame 503 does not deviate during lateral movement, thereby achieving precise lateral positioning of the flipping mechanism 6.

[0025] Please see Figure 2 and Figure 3 As shown, two electric push rods 505 are fixedly installed on the inner wall of the movable frame 503. The electric push rods 505 have the characteristics of adjustable stroke, large thrust, and high precision. The output end of the push rods 505 is fixedly connected to the mounting frame 506. The mounting frame 506 is formed by bending stainless steel plate, which has a stable structure and can bear a certain weight. The outer surface of the mounting frame 506 is slidably connected to the inner wall of the movable frame 503. The telescopic movement of the electric push rods 505 can accurately adjust the longitudinal height of the mounting frame 506 and the flipping mechanism 6 to adapt to the needs of different raw material quantities and cooling stages, ensuring that the arc plate 606 is always in the optimal working position when rotating and flipping the raw materials, and fully contacting the raw materials to avoid excessive disturbance.

[0026] Please see Figure 4 and Figure 5As shown, the housing 1 has a flipping mechanism 6 inside. The flipping mechanism 6 specifically includes a second motor 601 fixedly mounted on the top of the mounting bracket 506. The second motor 601 is a small DC motor with adjustable speed and smooth operation. Its output end is fixedly connected to a rotating shaft 602, which is made of stainless steel with a chrome-plated surface to enhance its wear resistance and corrosion resistance. The rotating shaft 602 rotates with the mounting bracket 506 via bearings, ensuring flexible rotation. A driving bevel gear 603 is fixedly connected to the end of the rotating shaft 602 away from the second motor 601. The driving bevel gear 603 is a steel gear with a precisely calculated module and number of teeth, enabling it to mesh well with the driven bevel gear 604 and transmit stable power. The outer surface of the driving bevel gear 603 meshes with the driven bevel gear 604, which is also a steel gear, with a material matching the driving bevel gear 603 to ensure reliable and durable meshing. A limiting shaft 605 is fixedly connected to the outer surface of the driven bevel gear 604. The outer surface of the limiting shaft 605 rotates with the inner wall of the mounting bracket 506 via a bearing, ensuring smooth and stable rotation. An arc-shaped plate 606 is fixedly connected to the outer surface of the limiting shaft 605. The arc-shaped plate 606 is made of food-grade silicone, which is soft and elastic. Its shape is designed to match the curvature of the bottom of the cooling drawer 3, allowing the raw materials to be gently turned over during rotation, avoiding damage to the raw materials, while ensuring that the raw material particles are fully dispersed, so that heat can be dissipated quickly and evenly.

[0027] In this embodiment, a temperature sensor 7 is fixedly installed on the inner wall of the shell 1. The temperature sensor 7 is a high-precision thermistor sensor, which can monitor the temperature inside the shell in real time and accurately, and feed the temperature signal back to the external controller. The controller automatically controls the operation of motor 501, motor 601 and cooling fan according to the preset temperature range, so as to realize intelligent cooling process control, further optimize the cooling effect, effectively shorten the cooling time, reduce the risk of microbial growth, provide a stable and suitable raw material temperature environment for subsequent fermentation, and significantly improve the quality and production efficiency of rice wine.

[0028] In use, the steamed rice wine raw material is poured into the cooling drawer 3 and pushed into the housing 1. The motor 501 is started, and its output end drives the adjusting screw 502 to rotate, causing the moving frame 503 to move laterally under the guidance of the guide rod 504, thereby achieving the lateral positioning of the turning mechanism 6. The electric push rod 505 extends and retracts to adjust the longitudinal height of the mounting frame 506 and the turning mechanism 6. The motor 601 is started, driving the rotating shaft 602 to rotate, which drives the active bevel gear 603 to mesh with the driven bevel gear 604, thereby causing the limiting shaft 605 and the arc plate 606 to rotate to turn the raw material. The temperature sensor 7 monitors the temperature in real time and provides feedback. The cooling fan inside the ventilation window 4 is turned on to accelerate the air circulation in the housing 1. Working together with the turning mechanism 6, it promotes rapid and uniform heat dissipation of the raw material. When the temperature drops to a suitable range, the device is turned off, and the cooled raw material is taken out for the subsequent fermentation process.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
