Description

Baking tray

BACKGROUND OF THE INVENTION

The invention relates to a baking tray to be used on two sides, particularly for baking dough products. Known baking trays comprise a rectangular circumferential frame in which a carrier for dough products has been placed. Said baking tray can be flat, but also curved for instance for baking baguettes. The baking tray may be a closed piate, however a perforated carrier is also possible, optionally provided with a non-stick coating.

English patent application 2 193 626 describes a baking tray comprising a first carrier supporting a flat product and a supporting second carrier provided with cavities, wherein the first and second carrier are placed back to back against each other and wherein the first and second carrier are surrounded by a framework having a C-shaped cross-section. If so desired the first or second carrier can be used, depending on which side of the baking tray faces upwards.

A further baking tray for double-sided use having a circumferential frame is described in GB 426,979.

A drawback of the known double-sided baking trays is that the products need to be removed from the baking tray by means. This is usually done using a special device provided with a series of gripping elements for engaging onto the dough products. Examples of such gripping elements are suction cups.

The inventor thus acknowledged that there is a need for a double-sided baking tray wherein the products, particularly baked-off dough products, on the baking tray can easily be removed from the baking tray. It is an object of the invention to provide such a double-sided baking tray.

SUMMARY OF THE INVENTION

According to a first aspect the invention for that purpose provides a baking tray for double-sided use, comprising a carrier for supporting dough products and a frame surrounding the carrier and connected thereto, wherein the frame projects above and below the surface of the carrier, characterised in that the frame at a first side of the carrier comprises a first recess and wherein the frame at the other three sides projects above the surface of the carrier, wherein the frame at the location of the first recess has a level that is situated at the same level as or below the surface of the carrier, wherein the frame at a second side of the carrier comprises a second recess and wherein the frame at the other three sides projects below the surface of the carrier, wherein the frame at the location of the second recess has a level that is situated at the same level as or above the surface of the carrier or trays.

The invention thus provides a double-sided baking tray that in a very simple manner provides for the need mentioned above.

The baking tray according to the invention can be used on two sides, wherein the switch from the one to the other side takes place by simply turning the entire baking tray, a rotation of substantially 180 degrees about an axis in the plane of the baking tray. In both conditions of the baking tray the substantially circumferential edge at a side of the baking tray is provided with a recess for via said recess sliding off the dough products from the baking tray. The other three sides on each side of the carrier form an upright edge or retaining wall that prevents the dough products from sliding off along said edge.

In the first position of use the baking tray is provided at a first side with a recess in the frame, which recesses make it possible for at that location offering passage to the dough products when sliding off the dough products from the carrier. In the turned second position of use of the baking tray the frame at the location of the second recess will have a level that is situated at the same level as or below the surface of the carrier or trays. In this way the dough products are offered a second passage for sliding off the dough products from the tray in the turned condition of the baking tray.

In that case both opposite surfaces of the carrier can be adapted for supporting dough products, or the carrier can be composed from two carrier members placed back to back arranged for supporting dough products.

In one embodiment the carrier and frame can be turned as one unity to switch from using a first side of the carrier to using a second side of the carrier. The baking tray can thus in its entirety also be turned mechanically a fully automatic assembly for dough treatment.

In one embodiment the carrier is permanently connected to the frame. In that case the carrier can be connected to the frame via a screwed connection, welded joint or glued joint.

One embodiment comprises a substantially rectangular baking tray, wherein the first and second side are provided with the first and second recess, respectively, and wherein the frame at the other three sides projects above and/or below the surface of the baking tray. In that way the sliding off along another side than the first or second side can be substantially prevented.

In one embodiment the first and/or second recess extend over substantially the full length of the first side and/or second side, respectively. In that way there are substantially no obstructions along said first and/or second side that may hamper the sliding off of the dough products.

In one embodiment the recesses for the upper side of the baking tray and the recesses for the lower side of the baking tray are placed at opposite sides of the baking tray. This embodiment makes it possible that the position of the sides with recesses with respect to the dough treatment device, in which the device according to the invention is placed, is maintained when rotating the baking tray over 180 about an axis extending substantially parallel to the sides with the recesses.

In an alternative embodiment the sides of the frame with recesses for the upper and lower side, respectively, of the baking tray are situated on the same side of the device. In said embodiment the orientation of the side with recesses for sliding off the dough products here in a dough treatment machine remains substantially the same in case of a rotation of the baking tray about an axis extending substantially perpendicular to the sides with recesses.

In a further alternative embodiment the first side of the carrier is placed substantially transverse to the second side of the carrier. In this embodiment the orientation of the side with recesses for sliding off the dough products here in a dough treatment machine remains substantially the same in case of a rotation of the baking tray about an axis extending substantially diagonally over the baking tray.

Due to a suitable choice of position of the first and second sides and the axis of rotation of the baking tray, the orientation of the side with recesses for sliding off the dough products can also be chosen differently, for instance for sliding off products to different sides depending on the use of the first or second side of the carrier.

In one embodiment the carrier, at least its side, is situated at the location of the recess, at least partially abuts the frame. In one embodiment the carrier, at least its side, at the location of the recess, at least partially rests on the frame. In this way at the location of the recess an adequate support of the carrier is effected.

In one embodiment the carrier abuts the frame over substantially the full length of the recess. In one embodiment the frame at the location of the recess, substantially follows the contours of the carrier. The carrier, substantially over the full length of the recess, can be supported by the frame. The carrier can also be attached to the frame over the full length of the recess. According to a second aspect the invention provides a baking tray for double-sided use, comprising a frame and a carrier connected to the frame having a bearing surface for dough products, wherein the frame comprises substantially equal U-shaped first and second frame members, each frame member having a base side and two arms placed substantially transverse to the base side, wherein the frame members are placed on one another, particularly on both sides of the carrier, and wherein the arms of the first frame member, substantially over their full length, are placed adjacent to the arms of the second frame member. In one embodiment the base side of the first frame member and the base side of the second frame member can be placed at opposite sides of the baking tray. In one embodiment the base side of the first frame member and the base side of the second frame member can be placed at the same side of the baking tray.

According to a third aspect the invention provides a baking tray for double-sided use, comprising a frame and a carrier connected to the frame, the carrier having a bearing surface for dough products, wherein the frame comprises U-shaped first and second frame members, each frame member having a base side and two arms placed substantially transverse to the base side, wherein the base side of the first frame member substantially has the same length as an arm of the second frame member, wherein the frame members are placed on one another, in particular on both sides of the carrier, and wherein a base side of the first frame member, substantially over its full length, is placed adjacent to the arm of the second frame member.

According to a fourth aspect the invention provides a baking tray for double-sided use comprising a carrier and a frame surrounding said tray, wherein the frame for both surfaces of the carrier projects above the surface of the carrier, and wherein the frame for each side of the carrier at at least one side is provided with a recess for via said recess sliding off the baking products from the baking tray side in question.

According to a fifth aspect the invention provides a dough treatment device, particularly a baking oven, comprising one or more of the baking trays described above. According to a further aspect the invention provides a method for manufacturing a baking tray for double-sided use, comprising a frame and a carrier having a bearing surface for the dough products on both sides, wherein the frame comprises substantially equal U-shaped first and second frame members, each frame member having a base side and two arms placed substantially transverse to the base side, wherein the method comprises the step of: placing the first and second frame member on one another on both sides of the carrier, and wherein the arms of the first frame member, substantially over their full length, are placed adjacent to the arms of the second frame member, attaching the first frame member to the carrier and/or to the second frame member.

According to a further aspect the invention provides a method for manufacturing a baking tray for double-sided use, comprising a frame and a carrier having a bearing surface for the dough products on both sides, wherein the frame comprises U-shaped first and second frame members, each frame member having a base side and two arms placed substantially transverse to the base side, wherein the base side of the first frame member has substantially the same length as an arm of the second frame member, wherein the method comprises the step of: placing the first and second frame member on one another on both sides of the carrier, wherein the base side of the first frame member, substantially over its full length, is placed adjacent to the arm of the second frame member, attaching the first frame member to the carrier and/or to the second frame member.

By means of said methods a baking tray for double-sided use can easily be made using two U-shaped frame members, which in one embodiment can be substantially equal in shape and dimensions, and a carrier having a bearing surface for dough products on both sides.
