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
(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
(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
(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
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,
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
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
