Definitions
- the present invention relates to a method of applying a spreadable coating such as a thin spread of butter or the like to a food slice such as a slice of bread, and also to an apparatus for applying a spreadable coating to a food slice.
- the second known method is non-contact buttering in which butter is sprayed or thrown onto the surface of a slice of bread, either from a nozzle through which the butter is pumped or from a spinning disc.
- softened butter is pumped onto the disc and the effect of centrifugal force flings the butter off the edge of the disc and onto the slice of bread passing beneath the disc.
- a method of applying a spreadable coating to a passing slice such as a bread slice, comprising forming a layer of the spreadable coating material on a moving applicator member, and transferring the spreadable coating material from the applicator member to a slice to be coated, wherein the layer applied to the applicator member is formed by a means of a doctor blade which is stationary relative to the applicator member, characterised in that a moving feed member is used to apply a layer of spreadable coating material to the applicator member and is loaded with a layer of spreadable coating material by virtue of passing close to said doctor blade, and in that the thickness of the layer applied to the feed member is greater than the thickness of the layer which it applies to the applicator member
- the food slice to be coated is a slice of bread and the spreadable coating is of butter, margarine or other spread which is held in a reservoir and released on to the feed member in the form of a relatively thick layer which is then transferred in the form of a relatively thin layer on to an applicator member which in turn applies the layer to the food slice.
- the spreadable coating is of butter, margarine or other spread which is held in a reservoir and released on to the feed member in the form of a relatively thick layer which is then transferred in the form of a relatively thin layer on to an applicator member which in turn applies the layer to the food slice.
- a further aspect of the present invention provides an apparatus for applying a spreadable coating to a food slice, comprising means defining a path for the food slice to be coated, a coating member arranged to move closely past said path to contact a food slice moving along said path, and means, including a doctor blade, for applying a spreadable coating material to said applicator member, characterised in that the means for applying a spreadable coating material to the applicator member further includes a feed member mounted for movement past said doctor blade and past the path of movement of the surface of said applicator member, such that the distance between the doctor blade and the feed member at the point of closest approach therebetween is greater than the distance between the feed member and the applicator member at the point of closest approach therebetween.
- the applicator member is a roller which is driven for rotation relative to the path of a passing food slice to be coated.
- the feed member is itself a roller which rotates with its surface moving past the doctor blade so that spreadable coating material held back by the doctor blade can be released as a relatively thick layer on to the surface of the feed roller and can then be transferred as a relatively thinner layer on to the applicator roller.
- the rate of rotation of the feed roller is variable in order to control the flow rate of spreadable coating material to the surface of the applicator roller.
- the feed roller and applicator roller rotate in the same direction so that the surfaces of the feed and applicator rollers at their closest point move in opposition to one another.
- the food slice to be coated can move relative to the applicator roller such that the direction of motion is either co-current with the surface of the applicator roller or counter current therewith, at the point of closest approach.
- the rate of rotation of the feed roller is less than that of the applicator roller. More advantageously the surface speed of the feed roller is less than that of the applicator roller.
- Figure 1 shows a side elevational partly schematic, view of a conventional bread buttering apparatus in use
- Figure 2 is a corresponding view of a bread buttering apparatus in accordance with the present invention.
- Figure 1 shows a conventional contact buttering system with a bread slice 1 moving leftwardly past a clockwise-rotating applicator roller 2 such that, at the point of closest approach of the bread slice to the applicator roller 2 (the bottom of the circular path of travel of the surface of the applicator roller 2), a coating of butter, margarine or other spreadable material is transferred from the applicator roller to the bread slice 1.
- a doctor blade 3 is positioned in the upper portion of the path of travel of the surface of the applicator roller and holds back a reservoir 4 of butter or the like which can gradually pass through the gap between the doctor blade 3 and the applicator roller 4 in the form of a layer on the surface of the roller 2.
- the relatively thick layer of spreadable butter on the feed roller only needs to move slowly round to the point of closest approach between the feed roller 5 and the applicator roller 2a in Figure 2 in order to provide, on the cylindrical surface of the applicator roller 2a, a layer which will have substantially the same thickness as that on the applicator roller 2 of Figure 1.
- the applicator members are described as being in the form of continuously rotating rollers, the rollers could be caused to index in rotation rather than to rotate continuously, and indeed the applicator member need not be in the form of a roller 2a, nor need the feed member be in the form of a roller 5.
- Other constructions of feed member and/or applicator member which nevertheless exhibit the difference in the approach distance of the feed member to on the one hand the widely spaced doctor blade 3a and on the other hand the closely spaced applicator member 2a can be evident.
- the slice can be replaced by any other material requiring application of a coating, for example scones or toast, and likewise the material to be applied as a coating may be any spreadable material normally spread on bread, for example margarine, other spreadable fat, peanut butter or honey.
