Affecting the rate of alcohol production of starch in the first case, too little dissolved oxygen, if it is liquid fermentation, it is found that there is less bubbling, no fermentation, and solid-state fermentation is found to be slowly warming up. At this time, it is necessary to consider whether it is insufficient dissolved oxygen; In the second case, too much dissolved oxygen, the most prone to dissolved oxygen is rancid, because most of the bacteria are aerobic bacteria, if the number of bacteria in the early stage, the fermentation will directly fail. 3. Control the fermentation temperature. The "drunk" of the koji is suitable for growth and reproduction at 25-28 degrees (it is difficult to control the temperature in this range in winter, and the temperature can be controlled at 20-30 degrees in practice) The temperature of the fermented material "drunk" should not exceed 36 °C (the temperature will often exceed 36 degrees a few days before fermentation, you should always observe it, if you exceed it, don't worry, think of cooling down, allow a short time over 36 °C). According to this requirement, when the temperature is high in summer, attention should be paid to ventilation and cooling. When the temperature is low in winter, it is necessary to pay attention to heating and heat preservation. Remember that the top temperature during the fermentation process should not exceed 36 °C for a long time. 4, inhibit the growth and reproduction of bacteria Inhibition of bacteria mainly includes two aspects: First, sterilization, is to do a good job of disinfection and environmental sanitation; Second, to inhibit the growth of bacteria, so that the bacteria will not grow quickly. 1) Disinfect the fermentation vessel, fermentation water, cooling bed, operating tools, etc. The simpler aspect is to disinfect with hot water. If the bacteria are more serious, it can be disinfected with quicklime or potassium permanganate. 2) When the bacteria enters the oxygen or the temperature of the fermented material is too high, it will multiply. As long as the work is done in this way, the bacteria will not patronize your wine cellar. 5. The cooling and sealing properties of the brewing equipment are not good. In addition, if the control of the fire is improper, the cooling and the sealing are not good when using the brewing equipment, the wine will volatilize a part of the distillation process, which will directly affect the wine yield.
The Pedicure Spa Chair
provides a suitable location for people to provide foot care services. It is
divided into two types. One is an Adult Back Massage Pedicure Spa Chair, and
the other is a children's pedicure spa chair. Its function is
1. Promote blood circulation.
In general, body temperature has a close relationship with blood circulation,
low body temperature, low blood circulation, and elevated body temperature,
blood circulation will also flourish. The hot water foot bath can improve foot
blood circulation, the warming effect of water, can expand the blood vessels of
the foot, increase the skin temperature, thereby promoting foot and systemic
blood circulation; at the same time, the hot water foot bath also increases the
blood flow velocity and flow of the foot, This improves heart function and
reduces heart load.
2. Promote
metabolism. The hot water foot bath promotes the blood circulation of the foot
and the whole body. As the blood circulation increases, it regulates secretion
of various hormones by various endocrine glands, such as thyroid hormone
secreted by the thyroid gland, adrenal gland hormone secreted by the adrenal
gland, etc. These hormones can Promote metabolism.
3. Eliminate fatigue.
When the human body is fatigued, foot blood circulation, metabolic end
products, calcium salts, lactic acid microcrystals and other substances are
deposited first. When the function of an organ of a human body is abnormal or
ill, due to the influence of pathological reflexes, the blood circulation of
the foot is worsened, and deposition is more likely to occur. Hot water foot
bath is the simplest and most effective way to eliminate physical fatigue.
4. Improve sleep.
The feet are rich in nerve endings and capillaries, and they use hot water to
soak their feet for gentle stimulation of nerves and capillaries. This warm
stimulus stimulates reflection to the cerebral cortex and inhibits the cerebral
cortex. It is excited sympathetic nerves that smoothly transition to
parasympathetic nerves. After the parasympathetic nerve is excited, the person
is in a quiet resting state, thereby improving sleep and eliminating insomnia.
5. Health beauty,
raise brain care. Through hot water foot bath, meridians and blood can be
adjusted. At the same time, the blood vessels in the foot are expanded and the
blood volume is increased, so that the blood flow of the head is accelerated,
and the oxygen and nutrients required by the brain are supplemented in
sufficient time.
