Abstract

A sandwich buttering machine comprises a hopper 15 containing butter which is to be deposited on slices of bread 11a, 11b via an applicator roller 13. A regulator roller 14 is used to control the thickness of the butter being deposited, the position of roller 14 being adjustable by operation of screw 18. The thickness of butter may be further regulated by altering the relative speeds of rotation of rollers 13 and 14.

Description

improvements in food preparation This invention relates to food
preparation and more particularly to apparatus for preparing food products.
Apparatus for preparing food products, such as sandwich-making machines, are known in the art. In one such machine, butter is spread onto slices of bread via a rotating applicator roller whilst the bread slices are carried along on a conveyor. To regulate the amount of butter that is taken onto the applicator roller for transfer onto the bread slices, such machines typically use a stationary doctor blade which is positioned adjacent to the applicator roller. A problem with such arrangements is that the applicator roller can tend to pick up crumbs from the bread slices which are then carried round on its surface. If the crumbs are larger than the gap between the doctor blade and the applicator roller, they will become lodged on the doctor blade. The blockage that this causes results in an uneven spread of butter on the bread slices, because it produces lines or streaks where no butter is applied. The cure to this problem has been to ensure regular clearance of such crumb debris from the doctor blade.
The present invention aims to provide a better solution to this problem and provides apparatus for depositing a spreadable material such as butter on an edible substrate such as a slice of bread, comprising an applicator, means for forming a coating of said material on the applicator, the applicator being arranged to come into contact with the substrate for transferring material from said coating onto the substrate, the coating forming means including a regulator which defines in part a gap through which said material must pass en route to the substrate, and means for adjusting said gap to control the amount of material to be deposited on the substrate, wherein the regulator is in the form of a rotatable roller.
The invention also provides a method of depositing a spreadable material such as butter on an edible substrate such as a slice of bread, comprising forming a coating of said material on a rotatable applicator roller, bringing the applicator roller and substrate into contact with each other for transferring material from said coating onto the substrate, providing a rotatable regulator roller which defines with the applicator roller a gap through which the material must pass en route to the substrate, and adjusting said gap to control the amount of material to be deposited.
The invention further provides a method of depositing a spreadable material such as butter on a edible substrate such as a slice of bread, comprising forming a coating of said material on an applicator, bringing the applicator and substrate into contact with each other for transferring material from said coating onto the substrate, providing a rotatable feeder roller for supplying material to the applicator, providing a rotatable regulator roller which defines with the feeder roller a gap through which the material must pass en route to the substrate, and adjusting said gap to control the amount of material to be deposited.
By way of example, embodiments of the invention will now be described with reference to the accompanying drawings, in which: Figure 1 is a diagrammatic illustration of one form of apparatus according to the present invention, and Figure 2 is an alternative arrangement.
In Figure 1, a conveyor belt 10 carries slices of bread 11 a, 11 b in the direction of arrow A towards a buttering station 12. The buttering station 12 comprises an applicator roller 13, a regulator roller 14 and a hopper 15.
The applicator roller 13 is mounted for rotation about an axis 16 and its position above the conveyor belt 10 is adjusted to suit the bread slices 11 a, 11 b to which it is to apply butter. As seen in Figure 1, the direction of rotation of the applicator roller 13 is such as to follow the path of movement of the bread slices II a, 11 b during its contact with them, which is tangential. The application of butter to a bread slice by the applicator roller 13 in this manner is known in the art.
The regulator roller 14 is mounted for rotation about an axis 17, which is parallel to axis 16. A mechanism 18 mounts the regulator roller 14 so that its spacing from the applicator roller 13 can be adjusted. Both the regulator roller 14 and applicator roller 13 are driven to rotate, in Opposite directions as indicated by arrows B and C, but at the same speed.
Butter is supplied from the hopper 15 to the nip or gap between the applicator roller 13 and the regulator roller 14, as seen in Figure 1. The thickness of the resulting butter coating 19 on the applicator roller is determined by the gap between the two rollers 13 and 14.
With this arrangement, it will be seen that if the applicator roller 13 should pick up any crumbs from the bread slices 11 a, 11 b, these will not become lodged, but be forced through the gap between the applicator roller 13 and the regulator roller 14 by the action of their combined rotation. This avoids the problem of "streaking" associated with prior art devices and obviates the need to cater for regular clearance of crumb debris from the buttering station during its operation It also enables more efficient use to be made of the butter stock and hence less wastage.
The Figure 2 arrangement is similar to the Figure 1 embodiment, except that here a rotatably mounted feeder roller 20 is interposed between the hopper 15' and the applicator roller 13'. The feeder roller 20 and regulator roller 14' rotate in Opposite senses, as indicated by arrows D and B'. The regulator roller 14', and its adjustable mounting 18!, is essentially the same as that of the Figure 1 embodiment, but here it is arranged to co-operate with the feeder roller 20. That is to say, the adjustable gap here that controls the thickness of the butter coating 19' on the feeder roller 20 is between the regulator roller 14' and the feeder roller.
Butter is transferred from the coating 19' on the feeder roller 20 to the applicator roller 13' by virtue of the close proximity of these two rollers.
Applicator roller 13' rotates in the same direction as the feeder roller 20, as indicated by arrows C' and D, but at a faster circumferential speed. The effect of this is that the applicator roller 13' picks up a butter coating 21 from the feeder roller 20 which is of less thickness than the butter coating 19' on the feeder roller. Butter from this coating 21 is transferred to the bread slices 11 a, 11 b as they pass through the buttering station 12' in the direction of arrow A' in the same manner as the previous embodiment. The relative separation and speeds of rotation of the applicator and feeder rollers give a further measure of control of the amount of butter deposited on the bread.
As before, if applicator roller 13' should pick up any crumbs from the bread, these may travel round via the feeder roller back to the hopper supply. They will not form a blockage, however, as from there they will be forced to pass through the gap between the regulator roller 14' and the feeder roller 20 by the action of their combined rotation. Once again, therefore, the prior art problem of "streaking" is avoided.
Although the above description relates specifically to machines for buttering bread, it will be appreciated that the invention could relate to apparatus for depositing materials other than butter, for example spread or icing, onto substrates other than bread, for example rolls or cakes.
