摘要:
An apparatus for continuously drying unpackaged food products, in particular vegetables, comprises conveyor means (4) for conveying the products to be dried and circulating means (11,13,14) for feeding dry air on the product to be dried and for collecting wet air coming from the products, and being characterized in that the apparatus further comprises means (19) for dehumidifying the wet air, said means comprising an adsorption dehumidifier device.
摘要:
The present invention relates to a dryer (1) for free-flowing material to be dried (6), comprising a conveyor track which the material to be dried (6) is to pass through with at least one rotatable conveyor worm (2) in which a gas can be passed through the material to be dried (6), wherein the minimum of at least one rotatable conveyor worm (2) forming the conveyor track is surrounded over its entire circumference with a gas-permeable and material-impermeable casing (20). The new dryer (1) is characterized in that during operation of the dryer (1), the free-flowing material to be dried (6) fills only partially the cross section of the conveyor worm (2) inside the casing (20), in that the gas in a lower area of the conveyor worm (2) can be fed through the casing (20) into the inside of the conveyor worm (2) with the formation of a fluidized bed in the material to be dried (6), and in that the gas, after passing through the material to be dried (6) forming the fluidized bed, can be discharged into a top area of the conveyor worm (2) through the casing (20) thereof. The invention also relates to a method for operating a dryer (1).
摘要:
A rotary air impingement oven enables volume production of oil-free food products including those from root crops such as potato chips. The over contains a cage-like drum with perforate, containing product therein, are exposed to temperature and velocity controlled impinging process vapor which is withdrawn continuously during drum rotation. The food products within the drum are urged by an internal baffle towards the drum discharge during rotation

The machine comprises a hollow drum (9) having a perforated cylindrical surface (10) into which sheet plastic material is fed for washing and drying. Inside the drum, and parallel to its axis, one has a shaft (18) provided with a number of paddles (19) and projecting beaters (20) set at regular intervals along its entire length. The shaft (18) and the drum (9) are caused to rotate in like direction and at different speeds about their respective axes, the greater speed being that of the shaft. The process performed by the said machine enables a thorough wash and subsequent dry of large expanses of sheet plastic material priorto any shredding operation being carried out thereon for use in recycling.
