A kind of power-economizing method of freezing bean vermicelli
Technical field
The invention belongs to food technical field of starch noodle production, particularly relate to power-economizing method during a kind of freezing bean vermicelli.
Background technology
At present, bean vermicelli factory produce bean vermicelli time be all generally adopt physics open bar method, exactly normal temperature fresh vermicelli (bringing back to life aging rear) is moved on in freezer freezing, moisture content in fresh vermicelli is frozen, and then with after warm water powder (change ice), bean vermicelli bar just mutual adhesion, just can enter subsequent processing and dry or dried.The concrete equipment of freezing bean vermicelli and operation are: to produce the bean vermicelli factory of 5 tons of dry powder silks daily, refrigerant compression acc power is 30KW, freezer is that (every screen work is freezing fresh vermicelli 1000kg to 10 screen works, give money as a gift bean vermicelli 500kg), 5 o'clock of every morning, workman started to shift out in freezer the bean vermicelli being chilled to negative 10 DEG C, with warm water shower bean vermicelli to change powder machine, changed and went to freeze, about 1 hour used time, water consumption is about 30 tons; 6 o'clock workman is on 10 screen works in normal temperature (15 DEG C) fresh vermicelli 10 tons of loading freezers good to bring back to life (aging); 7 o'clock open refrigeration compressor and start freezing bean vermicelli, compressor about works 10 hours, when temperature in freezer is down to negative 10 DEG C, compressor quits work automatically, again the 10 screen work 10000kg fresh vermicellis being chilled to negative 10 DEG C are all shifted out freezer to 5 o'clock of morning workman, to change powder machine is changed it to get well with 30 tons of warm water again, this kind of freezing bean vermicelli method is 24 hours is a circulation.For a long time, bean vermicelli factory circulates like this for one day one day, and nobody thinks there is what weak point.
Inventor thinks, present promotion energy-conserving and environment-protective, freezing bean vermicelli method current in the industry still has the potential to be tapped in energy-saving and emission-reduction, method is had to create, so just invention devises a kind of power-economizing method of freezing bean vermicelli, object is power consumption when reducing freezing bean vermicelli, saves the water consumption when energy and minimizingization powder, reduces the waste of water resource.
Summary of the invention
Technical scheme of the present invention is divided into following operative step: 1. first the fresh vermicelli of first day total amount half is loaded in freezer and place every screen work; 2. open when refrigeration compressor is chilled to negative 10 DEG C and shut down; 3. should freeze well by half fresh vermicelli measured, then the frame place, space that the normal temperature fresh vermicelli of later half amount loads in freezer is placed; 4., after 1----2 hour, when the temperature recovery in freezer is to about 0 DEG C, shifts out the half amount fresh vermicelli first filled and use warm water shower powder to changing on powder machine; 5. the half amount fresh vermicelli opened in the freezing rear loading freezer of refrigeration compressor is shut down to when negative 10 DEG C; 6. again the fresh vermicelli of second day total amount half is loaded on the frame of space and place; 7. after 1----2 hour, when the temperature recovery in freezer is to about 0 DEG C, then the fresh vermicelli of later half for first day amount is shifted out freezer to changing on powder machine with warm water shower powder; 8. open refrigeration compressor, start freezing second day first half fresh vermicelli measured.
Its energy-saving and water-saving principle is: in freezer, remove to absorb the heat in half amount normal temperature fresh vermicelli of just warehouse-in with the half amount low temperature fresh vermicelli frozen, the normal temperature bean vermicelli that cold is loaded backward continues to deliver in relays down, and the half amount low temperature bean vermicelli frozen is heated up, thus can minimizing powder time the warm water amount that uses and shortening powder time, and half amount normal temperature fresh vermicelli temperature of rear loading can be made to reduce, thus required refrigerating capacity when reducing freezing, shorten the working time of compressor, reach the object of saving electric energy.
Its heat energy transfer mode is that the fan in heat radiation and freezer makes cross-ventilation.
With this kind of freezing bean vermicelli of method, the beneficial effect produced is, the bean vermicelli of freezing equivalent, and freezer power consumption only has original 60--70%, and water consumption when changing powder only has original 40---50%, energy-saving and water-saving successful.
Detailed description of the invention
Preferred the following step operation in tandem: morning 5 point, workman loads the normal temperature fresh vermicelli of first day output half in freezer and places every screen work, 2. during 5 thirty, open refrigeration compressor, work about 5 hours, storehouse temperature drop is to bearing 10 DEG C of just autostops, 3. 16 time, the frame place, space that the normal temperature fresh vermicelli of later half amount loads in freezer is placed, absorbs the heat in the normal temperature bean vermicelli in just loading freezer with the low temperature bean vermicelli frozen, 4. 18 time, shift out the temperature of first having frozen to have gone back up to close to the first half amount bean vermicelli thawed to changing on powder machine with warm water powder, because this half amount bean vermicelli has absorbed the heat of the later half amount bean vermicelli of two hours, so the change powder warm water that need use is little in freezer, 5. 18 thirty, open refrigeration compressor, only need work about 3 hours, Ku Wen just can be down to negative 10 DEG C of just autostops, the half amount normal temperature bean vermicelli loaded this is because rear in freezer has absorbed the cold partly measured in bean vermicelli first freezed within the time of two hours, be down to close to 0 DEG C by original normal temperature 15 DEG C, so refrigeration compressor shortens the working time, save electric energy, 6., during morning 5, workman reinstalls the half normal temperature fresh vermicelli of second day need freezing total amount on the space frame in freezer and places, 7. 7 time, the temperature recovery frozen loaded after shifting out first day to close to the half amount bean vermicelli thawed to changing on powder machine, just can change with a small amount of warm water, 8., during 7 thirty, open refrigeration compressor, only need work 3 hours, Ku Wen just can be down to again negative 10 DEG C, just autostop, remove to absorb the heat in half amount normal temperature fresh vermicelli of just warehouse-in with the half amount low temperature fresh vermicelli frozen like this, the normal temperature bean vermicelli that cold is loaded backward continues to deliver in relays down, remain a systemic circulation of total output within the time of one day like this, just divide in order to twice partial circulating, do not increase any equipment and do not increase workman's workload (still or originally taking on the quantity of freezer), (twice outbound and change powder time add up and are slightly less than original time quantum not increase workman's work working time total amount, this is because the change powder time decreased of the latter, water consumption decreases) when, just energy-saving and water-saving can be realized.
