Abstract
Abstract A plant for defrosting blocks (14) of frozen or deep-frozen food products, of the type with a flaking roller (101, uses a concentric-tube heat exchanger (52) to thaw the flakes, the heat exchanger having filter plates and a line for recirculating (72) the partially-thawed product to the tank (28) for collecting the flakes and to the exchanger (52) until the product has partially or completely thawed, substantially without thermal gradients within the thawed product.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
87 words
Plant for defrosting blocks (14) of food products, particularly deep-frozen eggs, of the type comprising a flaking roller (10) and means for thawing the flakes (14a), characterised in that these means comprise: - a tank (28) for collecting the flakes, - a heat exchanger (52), - means (48, 50, 72, 44) for transferring the flakes (14a) and the thawed product to the heat exchanger and for recirculating them to the collecting tank, so as to thaw the product quickly without localised temperature increases within the liquid mass.
Claim 2
Dependent Claim
87 words
Plant for defrosting blocks (14) of food products, particularly deep-frozen eggs, of the type comprising a flaking roller (10) and means for thawing the flakes (14a), characterised in that these means comprise: - a tank (28) for collecting the flakes, - a heat exchanger (52), - means (48, 50, 72, 44) for transferring the flakes (14a) and the thawed product to the heat exchanger and for recirculating them to the collecting tank, so as to thaw the product quickly without localised temperature increases within the liquid mass.
Claim 3
Dependent Claim
33 words
Plant according to Claim 1, characterised in that the collecting tank (28) has an agitator (36) and is provided at its upper end with a sprinkler-diffuser (44) through which the product is recirculated.
Claim 4
Dependent Claim
35 words
Plant according to Claim 1, characterised in that the exchanger (52) is of the concentric-tube type and includes a series of mesh filter elements (66) within the tube (64, 64a) in which the product flows.
Claim 5
Dependent Claim
46 words
Plant according to Claim 1, characterised in that the means include a volumetric pump (50) for pumping liquids with solids in suspension, a delivery tube from the tank (28) to the exchanger (52), and a recirculating tube (72) from the exchanger (52) to the tank (28).
Claim 6
Dependent Claim
35 words
Plant according to any one of the preceding claims, characterised in that it includes a belt conveyor (16) and a tipper-elevator (18) for the automatic supply of the blocks (14) to the flaking roller (10).
Claim 7
Dependent Claim
29 words
Plant according to any one of the preceding claims, characterised in that the collecting tank (28) includes a level sensor (46) by which the pump means (50) are governed.
Claim 8
Dependent Claim
28 words
Plant according to any one of the preceding claims, characterised in that it further includes an automatic washing unit which operates at the end of the working cycle.
Claim 9
Dependent Claim
30 words
Plant according to Claim 3, characterised in that the filter elements (66) of the series have meshes which decrease progressively in size in the direction of advance of the product.
Claim 10
Dependent Claim
79 words
Process for defrosting blocks (14) of food products, particularly deep-frozen eggs, of the type including the steps of reducing the blocks to flakes (14a) and thawing the flakes themselves, characterised in that the thawing is achieved by means of pumping the flakes and the thawed product from a collecting tank (28) to a heat exchanger (52), recirculating the product from the exchanger to the tank until the product has thawed to the desired extent, and removing the product itself.
Claim 11
Dependent Claim
79 words
Process for defrosting blocks (14) of food products, particularly deep-frozen eggs, of the type including the steps of reducing the blocks to flakes (14a) and thawing the flakes themselves, characterised in that the thawing is achieved by means of pumping the flakes and the thawed product from a collecting tank (28) to a heat exchanger (52), recirculating the product from the exchanger to the tank until the product has thawed to the desired extent, and removing the product itself.
