Abstract
Method and device for frying products such as crisps in fat. The frying operation is carried out under vacuum conditions. After frying the crisps are centrifuged under vacuum as well. Centrifuging is realised by introducing the crisps from above in a rotating vacuum chamber. After centrifuging the crisps are directly discharged to a valve in the bottom of the vacuum charge to a sluice structure and are subsequently subjected to atmospheric pressure.
Description
- The present invention relates to a method for frying products such as slices in fat.
- Such a device is known from U.S. Pat. No. 5,988,051A.
- It is known in the prior art to carry out the frying process at reduced pressure in a vacuum vessel, which makes it possible to work with a lower fat temperature. On the one hand, this extends the service life of the fat and, on the other hand, the absorption of fat is limited. It is known in the prior art to subsequently subject crisps fried in such a way to a mechanical vibration treatment or the like outside the vacuum vessel used in the process, in order to remove the last of the fat from the slices. Steam is added in the process. One problem here is that the mechanical energy supplied to the slices must be limited. The fact is that if this energy supply is too great, the brittle, hardened, just baked crisps will break, which is not desirable. This means that in practice only the outside of the crisps is heated and fat removed from them there.
- If, for example, potato crisps are being fried, it is possible to achieve a fat percentage of approximately 24% using such a method.
- U.S. Pat. No. 5,988,051 discloses removal of further fat from the products by subjecting said products to a centrifuge treatment in a vacuum chamber. After introduction of the product in the centrifuge, the centrifuge is started and fat material is removed. Subsequently connecting with the vacuum vessel is closed whilst connection is made to the surrounding atmosphere. The centrifuge body together with the product is removed from the centrifuge chamber and the product is removed from the centrifuge.
- It has been found that despite these chips still tend to agglomerate, resulting in rejection of chip material.
- The invention aims to obviate these drawbacks.
- According to the invention this is realised with a method for frying products, comprising the exposure of said products to heated fat at reduced pressure, comprising introduction of the products to be fried through an inlet sluice construction of a vacuum vessel, in which fat is present, frying such products and removing said products through an outlet sluice construction, wherein vapors, comprising water vapor, in said vessel are discharged by a vacuum pump from said vessel, wherein the discharge of vapors, the water vapor is condensed before entering in the vacuum pump.
- It is proposed according to a first aspect of the invention that in the discharge of vapours, the water vapour is condensed before entering any vacuum pump. Because of removal of water by condensing water vapour the total vapour volume is substantially decreased meaning that it is not necessary to use heavy vacuum pumps. Such condensation can be produced by compressing the water vapour slightly using simple fans and guiding it along a cooled surface. It has been found that condensation occurs in the process. Of course, this measure can also be applied in the case of other vacuum installations known in the prior art.
- According to a preferred embodiment of the invention after closing the connection with the vacuum vessel and opening the centrifuge chamber to the atmosphere immediately removal of the product is effected so that no agglomeration can occur.
- Agglomeration of material can be further prevented in that the rotating centrifuge member is provided with partions which extend radially. A further step to prevent agglomeration and to improve the quality of the product and to prevent breakage of the product comprises introduction of the product whilst the centrifuge is rotating. A further advantage can be obtained by removal of the product whilst the centrifuge is still rotating.
- According to a further preferred embodiment of the invention, the centrifuge means and more particular the rotatable container in which the chips are received is tilted relative to the vertical preferably with an angle of about 30° relative to the vertical. This improves both loading and unloading more particular if the centrifuge still rotates.
- Because centrifuging is a batch wise operation preferably two centrifuges are provided being alternatively operated allowing for continuous feed of chips and other material to the centrifuges
- Means for regulating the residence time of the crisps in the vacuum vessel as uniformly and as accurately as possible can be present in the vacuum vessel. Combinations of conveyor belts and rotating wheels in the fat bath can be present for this purpose. Likewise, a separate belt, which forces the crisps into the fat, can be provided.
- In the course of frying many foods, owing to the increased temperature of the fat, considerable quantities of water vapour are produced at the time of entry into a vacuum vessel. This increases the pressure in the vessel. In the prior art it is proposed that a large number of heavy vacuum pumps be used in order to remove this water vapour and maintain the vacuum.
- The invention also relates to a method wherein the axis of centrifuging is about 30° relative to the vertical.
- The invention will be explained in greater detail below with reference to an exemplary embodiment illustrated in the drawing, in which:
-
FIG. 1 shows the device according to the invention diagrammatically in longitudinal section; and -
FIG. 2 shows cross section II-II according toFIG. 1 . - The device according to the present invention is indicated by 1 in the figures. This device is composed of a vacuum vessel 2 of considerable length. The latter is provided with an inlet sluice construction 3 and an outlet sluice construction 4. Fat is present and is indicated by 5. This fat can be stored in a separate container. The fat level is kept constant by means of a fat storage container 8 and a fat supply line 9. A circulation system for fat (not shown in any further detail), in which the fat is filtered and heated up, is present. For a fat customarily used for frying potato crisps, an optimum temperature is lower than approximately 136° C.
- Reference numeral 6 indicates a conveyor belt which moves through the liquid fat. Metering/control rollers, which accurately regulate the residence time of the product, are indicated by 7. A further conveyor belt is indicated by 16, and the arrow indicates that the latter is designed in such a way that it presses the products below the fat level. An elevator (extension of conveyor 6), which interacts with conveyor 18, is indicated by 17. This elevator opens on a
cross belt 30 which can be driven to move (as seen inFIG. 2 ) both to the left and to the right i.e. either tocentrifuge 19 or tocentrifuge 20. In this case the centrifuges are placed at an angle of about 30° to the vertical, in order to make as much use as possible of the space in the vacuum vessel and improve charging/discharging of chips.Sluice chambers valves rotating body 31 havingvertical separations 32. The bottom part of rotating bodies are provided bycones 33 which can move to and from the rotatingbody 31 to function as bottom valve. On the left side inFIG. 2 thebottom valve 33 is opened whilst it is closed on the right hand side.Drive motors 35 are provided for rotating the centrifuge body. - A vacuum pump is indicated by 13. A branch line for water vapour is indicated by 10. It contains a
pump 11 in the form of a fan. The fans used can be so-called Rootes blowers.Reference numeral 12 indicates a condenser, which is connected to a furtherexternal heat exchanger 15. A collection tank for water is indicated by 14, which collection tank can be isolated with respect to the vacuum in a manner not illustrated in any further detail, or which can be drained in some way. - The device described above functions as follows:
- The slices, such as potato slices, to be fried are introduced through the inlet sluice 3. During this process they fall downwards several tens of centimetres before reaching the
fat level 5. During this fall the pores of the material of the slices are opened by the vacuum and the evaporating water. The pores do not seal immediately when the slices come into contact with the fat 5: The oil temperature is preferably 120° C. The product is then conveyed on belt 6, the residence time being accurately regulated by the rollers 7. A maximum residence time of approximately 360 seconds is mentioned as an example. All this depends, of course, on all kinds of characteristics, in particular the thickness of the crisps and the temperature of the fat. The crisps are pressed below the fat level by means ofbelt 16. The crisps are subsequently deposited onbelt 30 and conveyed either tocentrifuge Bottom valve 33 of the related centrifuge is min the closed position. Charging of the centrifuge can be realised while the related centrifuge is still rotating at relative low speed. Because of theseparations 32 in the rotating centrifuge body the crisps are evenly distributed over de volume of the centrifuge body. After filling the related centrifuge the crisps are subjected to a centrifuging treatment incentrifuges adjacent sluice - At the end of the centrifuge treatment at opened valve 23 (and closed valve 34)
bottom valve 33 is opened. Because of the presence of such a bottom valve the crisps can immediately be discharged in forexample sluice 21 without the danger of conglomeration. Subsequentlyvalve 23 is closed and therelated valve 34 is opened discharging the crisps. In the meantime the other centrifuge, forexample centrifuge 20 is filled with new crisps. - By means of the device described above, it is possible to subject the crisps to a full frying treatment and treatment for the removal of fat in the course of an extremely short residence time. It has been found that the temperature of the crisps hardly rises above 60° during the frying, in view of the brief residence time. Moreover, the temperature of the crisps hardly falls after frying during the conveyance along
belts 17 and 18 and supplying to thecentrifuges - Although the invention is described above with reference to a preferred embodiment, it must be understood that numerous modifications can be made thereto. Adaptations can be made, depending on the product to be prepared and the specifications set for the product. Of course, it is also possible to carry out the various steps in separate vacuum vessels connected to each other in some way. These and similar modifications immediately spring to mind for a person skilled in the art on reading the above description, and lie within the scope of the appended claims.
