    500L/1000L/1500L Low price high quality 304 stainless steel beer fermentation tank

    High quality beer fermentation tank 1000L

    Beer technology related description

    The company strictly follow the German beer equipment production process, design and manufacture of domestic and international customer demand for beer equipment. Equipment work fine, good performance, convenient operation, is a high quality beer brewing. From the appearance to the internal quality of the same products have reached the advanced level of similar products, but also according to customer requirements, design a variety of beer equipment.


    Beer fermentation technology


    First, process flow

    Strain, Oxygen filling cold wort, fermentation, fermentation, before the main post fermentation, wine storage, fresh beer

    Two, fermentation technology

    1 Characteristics of conical tank fermentation method

    (1) at any time in the production process, the bottom of the bottom is in the shape of a production process, which requires the use of the yeast.

    (2) the tank itself has a cooling device for controlling the temperature of fermentation. Production is easy to control, the fermentation period is shortened, and the chance of contamination is few, the quality is stable.

    (3) Outside the insulation device of tank, tank can be placed in the outdoor, reduce construction investment, save area, is advantageous for the expansion.

    (4) the use of a closed tank, easy to wash CO2 and CO2 recycling, fermentation can be carried out under a certain pressure. You can do the fermentation tank, also do the wine storage tank, fermentation and wine storage can also be made one, called one fermentation method.

    (5) a CO2 gradient (i.e., a density gradient) is produced by the liquid height of the liquid in the tank. By cooling control, the natural convection of the fermentation liquid can be carried out, and the higher the tank is, the higher the convection is. Due to the presence of strong convection, the yeast fermentation ability is improved, the fermentation rate is accelerated and the fermentation period is shortened.

    (6) the fermentation tank can be controlled by meter or a microcomputer, which is convenient for operation and management.

    (7) Tapered tank below applies to fermentation, can also be applied to the fermentation.

    (8) CIP can be used for automatic cleaning device, convenient for cleaning.

    (9) the conical tank is convenient for processing (which can be processed in situ) and practical

    (10 Equipment capacity can be adjusted according to the production need to be flexible, capacity can range from 20 to 600 m, up to 1500m


    Working principle of conical tank and tank structure

    (1) working principle of conical fermenting tank

    Conical short fermentation cycle, fast fermentation tank fermentation reason is because of tapered tank fermented liquid fluid mechanics characteristics and the results of modern beer fermentation technology adoption.

    After inoculated yeast, due to the effect of condensation of the yeast, yeast cell density increased at the bottom of the tank, fermentation speed, increased the amount of carbon dioxide in the fermentation process, at the same time the static pressure generated in the fermented liquid of the liquid column height, also make the carbon dioxide content changes along with the fluid layer gradient in 4-3-1 (see chart), so the tank fermented liquid density also presents gradient change, in addition, because of tapered tanks outside the cooling device, the stages can be artificially controlled fermentation temperature. In the static pressure difference, fermented liquid density difference, the release of carbon dioxide, and the upper tank to cool the temperature difference (1 ~ 2 ℃) under the action of the driver, tank fermented liquid produced strong natural convection, enhances the yeast and fermenting liquid contact, promote the metabolism of yeast, the beer fermentation accelerated dramatically, beer fermentation cycle shortened significantly. In addition, due to the increased inoculation temperature, the temperature of beer fermentation temperature and yeast inoculation quantity, diacetyl reduction is also conducive to speed up the fermentation of yeast, so that the fermentation can be quickly.

    (2) the basic structure of the conical tank

    Tank top part

    Roof is a round arch structure, the central hole is used for placing removable large diameter flange, with installation of CO2 and CIP pipe and their fittings, roof installation of valves, overpressure valve and pressure sensors, such as tank inside a washing device, also have installed for the roof platform and channel of the operation.

    The roof of the tank is a round arch structure, the central hole is used to place the large diameter flange which can be removed to install CO2 and CIP pipe and its connecting parts. The tank top is equipped with vacuum valve, pressure valve and pressure sensor, etc..

    Part of the tank body

    Tanks for the cylinder, it is the main body of the tank. Fermentation tank height depends on the diameter of the cylinder and the height. Low pressure because of the large tank diameter, the diameter of the tapered tank generally no more than 6 m. Processing easier than roof tanks, tank external used to install the cooling device and thermal insulation layer, and leave the location of the installation temperature and load cell. Part of tank's cooling layer has a variety of forms, such as coil, miller, jacket, and divided into 2 ~ 3, connected to the cooling medium in pipe line, cooling layer coated with insulation materials such as polyurethane foamed plastics, insulation bag again outside a layer of aluminum alloy or stainless steel plate, there are also use the color steel plate as protective layer.

    Cone bottom part

    The angle between the conical bottom is generally 60 degrees to 80 degrees, 90 degrees to 110 degrees also have, but this multi fermentation tank for large capacity. Cone bottom fermentation tank height and angle, the angle of cone bottom part of the more high. The general tank of the cone base height of the total height of about 1/4, not more than 1/3. The outer wall of the conical bottom should be provided with cooling layer, which is deposited on the bottom of the cone. Cone bottom also should be installed in and out of the pipe, valve, mirror, temperature measurement, pressure sensor components, etc..

    In addition, the diameter and height of the tank is usually 1:2 ~ 1:4, and the total height is better than 16m, so as to avoid the strong convection, which affect the settlement of the yeast and the coagulation. Can the material can be made of stainless steel or carbon steel, if the use of carbon steel, the inner wall of the tank must be coated with no effect on beer flavor and non-toxic paint. The working pressure of the fermenting tank can be determined according to the working property of the tank, the working pressure of the general fermentation tank is controlled at 0.2 ~ 0.3MPa. The inner wall of the tank must be smooth, the inner wall of stainless steel tanks to polishing, coating for inner wall of carbon steel tank should be uniform, non convex and concave, convex non granular.

    (3) determination of the main dimensions of the conical fermenting tank

    The diameter and height ratio of the diameter and height of the cylinder is 1:1 ~ 4. The higher the ratio of the diameter to the larger, the more natural convection, the faster the yeast fermentation, but the yeast is not easy to settle, beer clarification difficult. The total height diameter and ratio of wort level should be 1:2, and the diameter of the cylindrical portion of the wort height ratio should be 1:1 ~ 1.5.

    The tank capacity tank capacity is bigger, the longer the wort during fermentation, the proliferation of many times, a long time, will cause the formation of diacetyl precursors increased, large quantity, long time reduction of diacetyl production. In addition, can also cause a wine, cleaning, back into the wort and other non production time prolonged, and the peak with the cold high, causing cooling tension. Because of the release of carbon dioxide and the production of foam, the effective volume of the tank is about 80% of the total.

    The cone angle is generally between 60 and 90 degrees, 60 degrees to 75 degrees, 60 degrees of common taper angle of stainless steel can be used, and the angle of the steel can be 75 degrees.

    The cooling jacket and the cooling area of a fermentation tank used for indirect cooling . General domestic use of half pipe, steel, arc tube jacket, or Miller's plate jacket at low temperature and low pressure (- 3 DEG C, 0.03MPa) with two times liquid refrigerant cooling abroad by using heat type (explosively) disposable refrigerant direct evaporative cooling. The disposable cold enzyme (such as ammonia evaporation temperature of - 3 to - 4 DEG C) after the evaporation pressure is 1.0MPa ~ 1.2MPa, the jacket pressure higher requirements. As the freezing point temperature of beer is generally 2 ~ 2.7, the temperature of cold media should be around 3. In China, 20% to 30% of alcohol water solution, or 20% propylene glycol water solution as refrigerant.

    According to the capacity of the tank, cooling can be used in the two paragraph or three paragraph. Cooling area according to the material of the tank, stainless steel material is generally 0.35 ~ 0.4m/m fermentation liquid, carbon steel tank is 0.5 ~ 0.62m/m. Cone bottom cooling area should not be too large, to prevent the formation of beer during the ice.

    The insulation layer material and small thermal conductivity, low quality, less water volume, non flammable properties such as protective layer insulation requirements. The commonly used thermal insulating material of polyamide resin, self extinguishing polystyrene, polyurethane, expanded perlite powder and slag cotton etc.. The thickness of the insulation layer is generally 150 ~ 200mm. The outer protective layer typically uses 0.7 ~ Aluminum Alloy 1.5mm thick plate, tin plate or 0.5 ~ 0.7mm stainless steel plate, corrugated plate is more popular recently.

    The tank pressure fermentation to produce a certain form of carbon dioxide pressure (the top of the tank, the tank pressure regulating valve) should be equipped with carbon dioxide, the tank top is provided with a safety valve. When carbon dioxide is discharged, the speed is too fast, the wine fermentation tank washing of dissolved carbon dioxide will cause appears negative pressure tank, so the vacuum valve must be installed. To use carbon dioxide or compressed air pressure inside the tank before the wine, to avoid the emergence of negative pressure, resulting in "flat tank fermentation tank".
