Description
Technical field
The present invention relates to that fruits and vegetables steam and the application of vacuum technology, particularly a kind of basin formula fruits and vegetables constant voltage blanching cooling processing apparatus and method for.
Background technology
In the fruits and vegetables deep-processing process, the processing technology of some product requires to carry out surperficial blanching to fruits and vegetables and handles.Purpose through this operation mainly contains two: the one, and can make the fruits and vegetables epidermis soft, the operation of being convenient to peel together down reaches easily removes the fruits and vegetables epidermis completely; The 2nd, can make fruits and vegetables reach the effect of the enzyme and sterilizing that goes out, in order to keep the original color and luster of fruits and vegetables and nutritional labeling.Therefore, the boiling blanching is the operation of a key, and the quality of its processing effect will directly have influence on the enforcement of subsequent technique, and products thereof final crudy.
The pre-digesting apparatus of traditional fruits and vegetables by the processing mode classification, mainly contains two kinds of hot water blanching mode and atmospheric steam blanching modes.Press the device structure classification, mainly contain two kinds of mesh-belt conveying formula and helix drum formulas.
Mesh-belt conveying formula equipment is that the guipure that the continuous circulation of a cover is carried moves in semiclosed case groove, can be full of hot water in the case groove, perhaps directly feeds atmospheric steam.Fruits and vegetables enter the operation of case groove under guipure drives, accept the blanching of hot water, or the blanching of steam.
Helix drum formula equipment is to carry body with the horizontal drum, and the cylinder barrel is covered with sieve aperture, inner band spiral, and material rolls within it and travels forward.The conveying cylinder outside is with the round cylinder slot body, and the cylinder cell body divides two halves groove up and down, covers sealing.This equipment can charge into hot water equally, or feeds atmospheric steam, is used for the hot water blanching, or steam blanching.
Though more than two kind equipments can satisfy general production requirement, crudy is not high, and has obvious defects.Hot water blanching temperature limited, heat time heating time is long; The pressure of atmospheric steam blanching is non-constant, difficult control of temperature.Dual mode is feeding mouth and the discharging opening of open type, and heat dissipation capacity is big, and power consumption is serious, and the material heating is inhomogeneous, has a strong impact on product quality.In addition, traditional blanching equipment does not all possess refrigerating function, and the fruits and vegetables after blanching is handled need enter next device and spray or soak and float cooling, its complex process, equipment investment cost height.
