Abstract
The invention discloses a method for cleaning saccharification tanks, and especially for cleaning saccharification tanks for producing high-maltose syrup or superhigh-maltose syrup or syrups with relatively long saccharification time. The method comprises the following steps: S1, cleaning a saccharification tank with hot water, and draining hot water in the saccharification tank; S2, heating the interior of the saccharification tank to transform residual hot water in the saccharification tank into water vapour, and maintaining the temperature inside the saccharification tank to be 82 DEG C-90 DEG C for 15 min-20 min; and S3, adding sterilization tablets into the saccharification tank to perform fumigating sterilization. The method for cleaning saccharification tanks is good in sterilization effect.
Description
Technical field
The present invention relates to the cleaning method of tank, relate in particular to the method for cleaning saccharifying tank.
Background technology
Saccharifying tank is very important equipment in sugar industry, for the saccharification step of sugar refining technology.After injecting step in sugar refining technology, before saccharification step, need saccharifying tank to clean, sterilize, then, could use saccharifying tank to carry out saccharifying.The method of cleaning saccharifying tank in prior art is that direct water rinses or direct same steam sterilization, then water is drained, and such method bactericidal effect is bad.
Summary of the invention
The problem that the present invention solves is the method for the existing cleaning saccharifying tank halfway problem that sterilizes.
For addressing the above problem, the invention provides a kind of method of cleaning saccharifying tank, the saccharifying tank particularly using in the product that saccharificatinn periods such as producing high malt sugar or superelevation maltose is grown.The method comprises the steps: S1, cleans the hot water of draining in saccharifying tank after saccharifying tank with hot water; S2, saccharifying tank inside heated and made hot water residual in saccharifying tank become water vapour, maintaining temperature in this saccharifying tank at 82 degrees Celsius～90 degrees Celsius, the time was at 15 minutes～20 minutes; S3, in saccharifying tank, add antibiotic tablet to fumigate saccharifying tank.
As a kind of possibility, in described step S2, keeping temperature in saccharifying tank is 20 minutes 82 degrees Celsius～90 degrees Celsius and retention time.
As a kind of possibility, described step S1 specifically comprises that twice use hot water cleans saccharifying tank, cleans the hot water temperature of saccharifying tank at 82 degrees Celsius～90 degrees Celsius at every turn, and the time keeps 15～20 minutes.
As a kind of possibility, in described step S1, the temperature of hot water is at 82 degrees Celsius～90 degrees Celsius, and hot water keeps 15 minutes～20 minutes in saccharifying tank.
As a kind of possibility, the temperature of described hot water is at 82 degrees Celsius～85 degrees Celsius, and the time is 20 minutes.
As a kind of possibility, described antibiotic tablet is the sulfur sheet boiling, fumigation time at least 30 minutes.
As a kind of possibility, the weight of described sulfur is 1kg:800m with the ratio of saccharifying tank internal volume
3～1000m
3.
Compared with prior art, the present invention has the following advantages:
1, because the present invention is by using hot water to clean saccharifying tank, also heating saccharifying tank inside makes residual hot water become water vapour, and keep temperature in saccharifying tank at 82 degrees Celsius～90 degrees Celsius, time was at 15 minutes～20 minutes, what continue by high temperature sterilizes to saccharifying tank, bactericidal effect is fine, in addition, fumigate saccharifying tank inside and saccharifying tank inside is sterilized again by antibiotic tablet, bactericidal effect is good, and particularly antibiotic tablet can sterilize to the position, dead angle of saccharifying tank inside after becoming flue gas.
2,, because the present invention cleans saccharifying tank by twice use hot water, like this, not only clean thoroughly, and bactericidal effect is good.
Accompanying drawing explanation
Fig. 1 is the flow chart that the present invention cleans the method for saccharifying tank.
The specific embodiment
By describing technology contents of the present invention, structural feature in detail, being reached object and effect, below in conjunction with embodiment and coordinate accompanying drawing to be described in detail.
Refer to Fig. 1, the saccharifying tank in present embodiment refers to the saccharifying tank using in the product that high malt sugar or superelevation maltose or saccharificatinn period grow producing, and the method comprises sequentially following steps:
S1: clean the hot water of draining in saccharifying tank after saccharifying tank with hot water.In this step, hot water not only can clean saccharifying tank, can also utilize the high temperature of hot water to sterilize to saccharifying tank, the temperature of hot water is at 82 degrees Celsius～90 degrees Celsius, hot water keeps 15 minutes～20 minutes in saccharifying tank, like this, can reach the object of cleaning and sterilizing.Technical staff finds, when the temperature of hot water is at 82 degrees Celsius～85 degrees Celsius (such as 82 degrees Celsius, 84 degrees Celsius, 85 degrees Celsius), holds time in the time of 20 minutes, and bactericidal effect is better, and the fuel expending still less; When hot water temperature is at 82 degrees Celsius～85 degrees Celsius (such as 82 degrees Celsius, 82.5 degrees Celsius, 83 degrees Celsius, 83.3 degrees Celsius, 84 degrees Celsius, 84.5 degrees Celsius, 85 degrees Celsius), while holding time at 20 minutes, bactericidal effect is best, and the fuel expending is minimum.In order to make, cleaning is more thorough and bactericidal effect good, can clean twice saccharifying tank with hot water, each hot water temperature who cleans saccharifying tank is at 82 degrees Celsius～90 degrees Celsius, time keeps 15～20 minutes, certainly, cleans the temperature of hot water at 82 degrees Celsius～85 degrees Celsius at every turn, time is 20 minutes, further, each temperature of cleaning is at 82 degrees Celsius～85 degrees Celsius, and the time is 20 minutes.
S2: saccharifying tank inside is heated and made hot water residual in saccharifying tank become water vapour, maintain temperature in this saccharifying tank at 82 degrees Celsius～90 degrees Celsius, the time was at 15 minutes～20 minutes.In this step, residual hot water heating is become to water vapour and utilize the high temperature in heating process to sterilize to saccharifying tank on the one hand, on the other hand, utilization adds thermogenetic heat can dry saccharifying tank.In order to make bactericidal effect better, scope is 82 degrees Celsius～85 degrees Celsius, and the time is 20 minutes.
S3: add antibiotic tablet to fumigate saccharifying tank in saccharifying tank.In this step, the antibiotic tablet using is sulfur, fumigation time at least 30 minutes.Sulfur fumigation can further thoroughly sterilize to saccharifying tank, because, sulfur fumigation and produce sulfur cigarette vapour, this sulfur cigarette vapour can sterilize to saccharifying tank inside (particularly position, dead angle).Bactericidal effect is not only relevant with fumigation time, also has relation with the volume of saccharifying tank and the weight of sulfur, and technical staff finds: the weight of described sulfur is 1kg:800m with the ratio of saccharifying tank internal volume
3～1000m
3time, bactericidal effect is better, that is to say, and the volume of every saccharifying tank inside is 100m
3,, 1kg sulfur can use for 8～10 saccharifying tanks.
In sum, the present invention uses hot water to clean saccharifying tank, also heating saccharifying tank inside makes residual hot water become water vapour, and keeping temperature in saccharifying tank at 82 degrees Celsius～90 degrees Celsius, the time, what continue by high temperature sterilized to saccharifying tank at 15 minutes～20 minutes, bactericidal effect is fine, in addition, fumigated saccharifying tank inside and saccharifying tank inside is sterilized again by antibiotic tablet, bactericidal effect is better.
