Description
Technical field
The present invention relates to a kind of fermentation unit, particularly relate to a kind of phase-change temperature control fermentation unit.
Background technology
When producing yeast wine, as leavening temperature control suitable, fermentation time proper extension, quality product is compared with high and taste is strong; As on the low side in leavening temperature, the time is short, and vinosity is just thin.So the fermentation period of various famous brands of wine, quality liquor is all long.
When producing liquor bran koji, make yeast and mold play one's part to the full in whole fermentation, must create suitable condition to them.The height of pit entry temperature is the important step that affects the yield of liquor.Leavening temperature is too high, and the miscellaneous bacteria amount reproduction of intrusion, by the effect of bacterium, can generate more bitter taste and peculiar smell, and the yield of liquor is also lower.Low temperature enters cellar for storing things, and because yeast is difficult for aging, miscellaneous bacteria is also difficult for breeding, and diastatic fermentation is thorough, and starch is fully utilized.Therefore, adopt low temperature to enter cellar for storing things and can guarantee the harmony of producing, voluminous wine.At high temperature season, often adopt artificial temperature adjustment and reduce pit entry temperature with iced water, and take to adjust proportion scale, reduce starch concentration, reduce wheat bran and distiller's yeast consumption, to shorten yeast phase, to adjust the measures such as working hour, reach the requirement that low temperature enters cellar for storing things as far as possible.
Artificial temperature adjustment, current method, has traditional buried Jiao Chi that utilizes soil to conduct heat, the air-conditioning ferment at constant temperature workshop that also has the central air conditioner system utilized to lower the temperature to fermenter.Traditional method energy-conserving and environment-protective, but need to select Seasonal Production, to pond, cellar for storing things temperature, also cannot accurately control.Air-conditioning ferment at constant temperature workshop need to have cryogenic freezing water to originate as cooling, and its cost and energy consumption are all higher.
Acidity is also the important indicator that white wine is produced fermenting process.Suitable acidity can be stablized to heat up in cellar for storing things and reaches fermenting process " front slow in very ", be conducive to starch pasting hydrolysis and generate fermentable sugar, under saccharomycetic effect, generate ethanol, the varied bacteria growing in stopping fermentation process, promotes that the various fragrance matters in wine generate.The relation of temperature and acidity: enter pond temperature high, prior fermentation heats up violent, raw sour amplitude is large, causes product acid fast, and acidity is high.If it is low to enter pond temperature, acidity conference causes fermentation calefaction slowly or does not heat up and " falling row ".On the contrary, if it is high to enter pond temperature, acidity is low, can cause heat up early stage too quickly, makes too raw sour amplitude strengthen, and reduces the yield of liquor, affects quality product.
Phase change material (Phase Change Materials, be called for short PCM), refers to vary with temperature and change form and the material of latent heat can be provided.Phase change material from solid-state become liquid state or become solid-state process from liquid state be called phase transition process.In phase transition process, phase change material will absorb or discharge a large amount of latent heat.So the amount of the phase change material accumulation of energy of unit volume, unit mass is far away higher than temperature difference energy storage.According to material, divide, phase change material can be divided into organic (Organic) phase change material and inorganic (Inorganic) phase change material; According to phase-change mechanism, divide, can be divided into hydration (Hydrated) phase change material and wax (Paraffin Wax) phase change material.Along with scientific and technological progress, scientific research personnel has developed multiple high-temperature phase-change energy-accumulation material at present gradually, and transformation temperature, can be between 5 ℃～40 ℃ higher than 0 ℃, and transformation temperature scope has contained the suitable temperature range of liquor fermentation.Large latent heat of phase change due to energy storage materials of phase change, the container made from energy storage materials of phase change has the characteristic of good maintenance temperature, typical example is put into (ice is exactly a kind of modal phase change material) in ice bucket beverage exactly, even if during the broiling summer, beverage also can keep low temperature for a long time.
CN203187666U discloses a kind of phase-change accumulation energy ferment at constant temperature tank on 09 11st, 2013, this tank body has adopted at conventional fermentor tank outer wall side bread and has covered the energy storage of one deck composite phase-change energy storage material, the coated thermal insulation layer insulation of outermost layer, make it have the effect of heating and absorbing and cooling temperature, reduce the consumption of the energy and the use of water coolant in fermentation.But this fermentor tank lacks the automatic measure of control of rational heat exchange, and snakelike heat exchange tube is mounted in fermentor tank, the temperature of the fermented liquid of parcel snakelike heat exchange tube outer wall must be infinitely close to the temperature of snakelike heat exchange tube outer wall, and the inevitable difference of the temperature of the fermented liquid far away apart from snakelike heat exchange tube outer wall is larger, and cannot control the temperature of phase change material, thereby can not be exactly by the uniform temperature fields of the fermented liquid in fermenter be controlled at suitable scope, and then affect the quality of the yield of liquor and wine.
