Abstract
The invention discloses a vacuum drying and dehydration device and production technology for small-scale pressed oil and solves the problems of cost up and the like caused by the fact that moisture is not completely removed, cake powder absorbs a large amount of hydrated oil and repeated filtering is performed. The vacuum drying and dehydration device and production technology are characterized in that the traditional water removal technique is changed into vacuum drying and dehydration, the device and the production technology have the advantages of reasonable structure, simplicity in operation, advanced technology, safety, environmental protection and the like and are particularly suitable for production of small-scale pressed strong-flavor oil products with higher requirements for flavor.
Description
Technical field
The invention belongs to edible oil manufacture field, refer more particularly to a kind of in the device of the higher little squeezing Luzhou-flavor oil product vacuum dehydration of local flavor requirement and production technique thereof.
Background technology
Bulk silo possesses the remarkable advantages such as construction duration is short, cost is low, floor space is little, manageability, at present generally adopt natural subsidence about little oil expression enterprise of coming unstuck, add cake powder, multiple times of filtration to reduce the water content in oil product, but this traditional method can cause moisture removal not thorough, cake powder absorbs a large amount of aquation oil, multiple times of filtration causes the consequences such as cost increase.Given this, we study and adopt dewatering technique to reach the quality standard of processed oil, can not cause again the rising of cost and loss simultaneously.
Summary of the invention
The object of the invention is for market provide a kind of rational in infrastructure, simple to operate, technique is advanced, the little oil expression vacuum dehydration device of safety and environmental protection and production technique thereof.
Technical scheme of the present invention is: it is made up of equipment such as oil tank, oil pump, interchanger, drying tower, canned-motor pump, water cooler, water-jet pump unit, freezing units, drying tower is vacuumized by water-jet pump unit, and is provided with mist eliminator betwixt.Between a canister and drying tower, be provided with plate-type heat exchanger, take out it by a point drum and steam source is provided, and be provided with by the plate cooler of unfrequented unit allocation between two canisters and drying tower, be communicated with drying tower by canned-motor pump.
Its production craft step is as follows:
(1) open vacuum water squirt pump, open mist eliminator again, site operation personnel notifies that Central Control Room operator start vacuum water and spray unit;
(2) open workshop and divide drum dry oil heater steam-pipe valve, adjusting air inflow quantity, be plate-type heat exchanger heating, regulate pressure, wait for oil-feed;
(3) open an oil strain pump and the oil of one canister is entered plate heater, ensure that being not less than 85 DEG C from well heater oil temperature out enters drying tower, wait for that oil level starts next step when arriving moisture eliminator first visor 2/3rds oil level;
(4) start freezing unit ice making water, frozen water enters plate cooler, and startup canned-motor pump slowly regulates and enters oil cooler, and oil outlet temperature is down to less than 45 DEG C, and oil enters two canisters notice product controls samplings.
The invention has the beneficial effects as follows: one is the process that the traditional sedimentation of cancellation is anhydrated, reduce oil emulsion, ensure that the amount of water of hydration process simultaneously, avoiding the moisture in order to ensure oil product, cause hydration process amount of water not enough and the high problem of the oil product phospholipids content that produces.Two is the filtrations reducing repeatability, reduces the consumption of filter paper and filter cloth, and consequent labour cost.Three is reduce steam consumption, reduces costs, increases income.Four is because the vacuum-drying time is short, can not have an impact to the local flavor of oil product.
Below in conjunction with accompanying drawing, the invention will be further described.
Accompanying drawing explanation
Fig. 1 is present invention process process blocks schematic diagram.
Embodiment
As shown in Figure 1, vacuum dehydration device is set up between a canister and two canisters, this device is made up of oil tank, oil pump, interchanger, drying tower, canned-motor pump, water cooler, water-jet pump unit, freezing unit etc., drying tower is vacuumized by water-jet pump unit, and be provided with mist eliminator betwixt, plate-type heat exchanger is provided with between a canister and drying tower, take out it by a point drum and steam source is provided, and be provided with by the plate cooler of unfrequented unit allocation between two canisters and drying tower, be communicated with drying tower by canned-motor pump.
Concrete production craft step is as follows:
(1) open vacuum water squirt pump, open mist eliminator again, site operation personnel notifies that Central Control Room operator start jet of water vacuum pump set, wait for on-the-spot consistent with the display of drying tower top vacuum pressure gauge, vacuum reaches (-0.085MPa) observation and checks pipeline, valve, flange, visor No leakage vacuum for a moment.
(2) open workshop and divide drum dry oil heater steam-pipe valve, use oil heater steam inlet valve regulated, open valve and slowly open steam boosting, to 0.1MPa, wait for oil-feed.Edible vegetable oil after first oil-feed to select after aquation one to filter according to oil quality, first closes oil foot tank and takes out boiled oil pump outlet valve, and can start an oil strain pump to the valve of aquation pot before ejector priming.
(3) an oil strain pump is opened to oil heater valve, start an oil strain pump to oil heater oil-feed, close drain by-pass simultaneously, regulate oil-feed admission pressure slowly to strengthen on a small quantity and ensure that well heater can not damage because pressure is excessive suddenly, ensure that being not less than 85 DEG C from well heater oil temperature out enters when moisture eliminator is waited for and had position to arrive moisture eliminator first visor 2/3rds oil level and start next step simultaneously, to again check each pipeline during this period, valve, flange, tensimeter, vacuum meter, thermometer, with or without difference, without doing next workshop section start preparation work after difference.
(4) canned-motor pump terminal valve is opened, start refrigerator ice making water and open the valve opening canned-motor pump cooling water valve circular wait oil-feed of refrigerator to oil cooler, open oil cooler oil-piping to canister valve, startup canned-motor pump slowly regulates and enters the guarantee of oil cooler pressure oil mass, oil cooler safety and stability, and oil outlet temperature is down to less than 45 DEG C.Oil enters a canister notice product control sampling.
