Description

Technical Field

[0001] This utility model belongs to the field of food processing technology, specifically relating to an ohmic heating beer gelatinizing pot. Background Technology

[0002] The gelatinization kettle is one of the core pieces of equipment in the pre-brewing stage of beer brewing, and its heating method has a significant impact on beer quality and production efficiency. Currently, most beer gelatinization kettles use heat conduction heating, transferring heat from the heating source to the materials inside the kettle via a heat transfer medium (such as steam). Because heat must be gradually conducted from the kettle wall to the interior of the materials, there is a delay in heat transfer, resulting in a slow heating rate and low efficiency throughout the gelatinization process. Heating via a heat transfer medium causes materials near the kettle wall to heat up quickly, while the materials in the central area heat up later, easily leading to localized overheating or underheating, and poor heating uniformity, thus affecting the fermentation effect and quality of the beer. Furthermore, heat conduction heating equipment has a relatively complex structure, high maintenance costs, significant heat loss during the heat transfer process, and low energy utilization.

[0003] Therefore, there is an urgent need to design an ohmic heating beer gelatinizing pot to solve the above problems. Utility Model Content

[0004] To address the problems of existing gelatinization pots where heating of materials via a heat transfer medium leads to delayed heating in the central area, resulting in localized overheating or underheating, this invention provides an ohmic-heated beer gelatinization pot. The pot includes a pot body and a lid. A stirring device is installed inside the pot, and two electrode plates are symmetrically arranged on the inner wall of the pot, electrically connected to the positive and negative electrodes respectively. The principle is based on treating the material as a conductor with resistance in a circuit. Under the influence of current, the Joule effect occurs, converting electrical energy into heat energy, thus achieving the heating purpose. This ohmic-heated beer gelatinization pot features rapid heating, good uniformity, energy efficiency, and ease of control.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An ohmic heating beer gelatinizing pot includes a pot body, a lid mounted on the pot body, a stirring device mounted inside the pot body, and two electrode plates symmetrically arranged on the inner wall of the pot body, with the two electrode plates respectively electrically connected to the positive and negative terminals of a power source.

[0007] Preferably, the pot body has a square structure and is made of ceramic.

[0008] Preferably, the electrode plates have a square structure and the two electrode plates are arranged symmetrically.

[0009] Preferably, the stirring device includes a motor and a stirring rod connected to each other, wherein the motor is located on the outside of the pot body.

[0010] Preferably, an insulation layer is provided on the outer side of the pot body.

[0011] Preferably, a steam valve is provided on the cover.

[0012] The beneficial effects of this utility model are as follows: This utility model discloses an ohmic heating beer gelatinizing pot. Compared with the prior art, the improvement of this utility model lies in:

[0013] (1) This utility model has two electrode plates symmetrically arranged in the pot body, and the two electrode plates are respectively connected to the positive and negative terminals of the power supply. During the addition process, the two electrode plates in the pot body and the material form a closed circuit, and the material can be regarded as the resistance in the closed circuit. When the current flows from the electrode plate connected to the positive terminal through the material into the electrode plate connected to the negative terminal to form a cycle, the process realizes the continuous conversion of electrical energy and thermal energy, thereby achieving the purpose of continuous heating of the material. Moreover, this heating method is different from the method of heating the material through the heat transfer medium. Its heating speed is significantly higher than that of heat conduction, and the heating uniformity is good and the efficiency is high, avoiding the occurrence of local overheating and underheating of the material.

[0014] (2) The present invention is also provided with a stirring device. By combining the stirring device with the electrode plate, the current is more evenly distributed in the material by turning the material, so that the material is heated synchronously as a whole, while preventing the material from settling and clumping, and ensuring that the material has a uniform shape.

[0016] The components include: 1. Pot body; 101. Support leg; 102. Mashing outlet; 103. Gravel outlet; 2. Cover body; 201. Buckle; 202. Raw material outlet; 203. Water inlet; 3. Stirring device; 4. Electrode plate; 5. Insulation layer; 6. Steam valve. Detailed Implementation

[0017] To enable those skilled in the art to better understand the technical solution of this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0018] Example:

[0019] See attached document Figure 1The ohmic heating beer gelatinizer shown includes a pot body 1, a cover 2 disposed on the pot body 1, a stirring device 3 disposed inside the pot body 1, and two electrode plates 4 symmetrically disposed on the inner wall of the pot body 1, and the two electrode plates 4 are electrically connected to the positive and negative terminals of the power supply, respectively.

[0020] Specifically, the pot body 1 has a square structure and is made of ceramic. The lid 2 is adapted to the pot body 1 and is also a square ceramic lid. The lid 2 and the pot body 1 together form a gelatinization pot. Several legs 101 are provided at the lower end of the pot body 1 to support the pot body 1 on the ground. The bottom of the inner cavity of the pot body 1 is inclined to facilitate the collection and discharge of waste.

[0021] The lower end of the pot body 1 is provided with a mash outlet 102 and a lees outlet 103 that communicate with its inner cavity. The mash produced by the gelatinization reaction flows out through the mash outlet 102 and is collected. It is then added to the saccharification pot for saccharification reaction. The lees outlet 103 is used to discharge the waste material after the gelatinization reaction and to clean the waste liquid inside the pot body 1.

[0022] The slag outlet 103 is located at the bottom slope of the inclined bottom of the pot body 1, which facilitates the collection and discharge of solid waste after reaction. Both the slag outlet 103 and the mash outlet 102 are equipped with valves, which can be used to control the opening and closing of the slag outlet 103 and the mash outlet 102 by opening the valves.

[0023] The inner wall of the pot body 1 is also provided with a heat insulation layer 5, which facilitates heat preservation of the pot body 1 and ensures the reaction temperature.

[0024] Furthermore, four fasteners 201 are fixedly installed on the four sides of the lid 2. These fasteners 201 allow the lid 2 to be fastened to the pot body 1. The fasteners 201 utilize existing products and structures. Specifically, the fastener 201 includes a mounting base fixed to the pot body 1 and a hook fixed to the lid 2. The hook is connected to the mounting base via a rotatable toggle mechanism. By operating the toggle mechanism, the hook can be locked or disengaged from the mounting base, thus achieving rapid sealing and opening of the lid 2. This toggle-type quick-opening fastener structure is a conventional technique in this field. It can utilize the T304 stainless steel KQ series quick-opening fastener from the well-known domestic brand "FEITE," or the Type 8705 quick-release handwheel from the German company "Bürkert," or similar products. Their structure and operating principle are also existing technologies and will not be elaborated upon here.

[0025] A steam valve 6 is also provided at the upper end of the cover 2. The steam valve 6 is located at the center of the cover 2 and is used to control the flow of steam into and out of the pot 1, thereby controlling the temperature and pressure inside the pot 1 and enabling emergency shutdown. In this embodiment, the steam valve 6 adopts existing products and structures, such as the JLB series stainless steel steam solenoid valve of the domestic brand "JULANG", or the VX21 series brass body / stainless steel valve core steam solenoid valve of the Japanese company "SMC". The structure and working principle of such valves (i.e., when energized, the electromagnetic force opens the pilot hole, the valve core moves upward to open the valve, and when de-energized, the pilot hole closes and the valve core moves downward to close the valve) are well-known technologies in the field. Their structure and control principle are also existing technologies, and will not be described in detail in this embodiment.

[0026] The upper end of the cover 2 is also provided with a raw material port 202 and a water port 203, which are used to add crushed malt and hot water required for beer brewing into the pot 1. After the gelatinization reaction is completed, cold water is added from the water port 203 to clean the pot 1.

[0027] Specifically, the electrode plate 4 has a square structure and there are two electrode plates 4. In this embodiment, the electrode plates 4 are symmetrically arranged on two symmetrical surfaces of the pot body 1, and the two electrode plates 4 are connected to the positive and negative terminals of the power supply device through wires respectively. When the power supply device is powered on, the current flows from the positive terminal through the material into the negative terminal to form a closed circuit, so that the material in the pot body 1 acts as the resistance in the closed circuit, thereby realizing the heating of the material in the pot body 1.

[0028] The power supply unit can be selected as model AY50 / 10K-31010 (manufactured by Xi'an Aoying Electrical Equipment Co., Ltd.), which has an adjustable output voltage range of 0 to 10000V and supports AC output frequencies of 50Hz to 1kHz and 10kHz. It adjusts the duty cycle of the output current through the switching control of solid-state relays, thereby achieving precise heating control.

[0029] The stirring device 3 includes a motor and a stirring rod connected to each other. The stirring rod is made of insulating material and has spiral stirring blades. The stirring blades are coated with an insulating coating, making them insulators as well. The stirring rod is located inside the pot body 1, and the motor is located at the lower outer side of the pot body 1, between the raw material inlet 202 and the water inlet 203. Preferably, the motor is located at the center of the lower end of the pot body 1. The output shaft of the motor is connected to the stirring rod through a coupling and drives the stirring rod to operate, so as to ensure that the materials are fully mixed and avoid local clumping or uneven heating.

[0030] The motor is located on the outside of the pot body 1 because an electric field exists inside the pot body 1, and the motor itself poses a risk of leakage / short circuit. The external design achieves physical isolation between the high-voltage electricity and the power source, and only requires sealing one stirring shaft, making it simple and reliable.

[0031] During use, the stirring device 3 turns the material to ensure that the current is distributed more evenly in the material, so that the material is heated synchronously as a whole, reducing local overheating, and preventing the material from settling and clumping, thus ensuring that the material has a uniform shape.

[0032] The preferred embodiment of the ohmic heating beer gelatinizing kettle is used as follows: First, the crushed malt and hot water required for beer brewing are added to the kettle body 1 through the raw material inlet 202 and water inlet 203 on the lid 2.

[0033] Then, the electrode plate 4 is energized and the motor is turned on. The motor drives the stirring shaft to stir the material in the pot 1. At the same time, the steam valve 6 is used to control the entry and exit of steam in the pot 1.

[0034] After gelatinization is complete, the mash produced by the gelatinization reaction flows out and is collected through the mash outlet 102. Finally, the waste material from the gelatinization reaction and the waste liquid from cleaning the tank are discharged through the lees outlet 103.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
