An oven utilizes a convective heat transfer mechanism for cooking the food products where the oven provides heated gas in the form of columns or streams and which are directed to at least one surface of a food product within the oven. Moisture, in the form of steam, is introduced within the convective heat transfer mechanism. Thus, an effective moisture environment can be created at and around the surface of the food product that is cooked under the influence of the heated gas/steam columns or streams. More preferably, steam is introduced within the convective heat transfer mechanism for creating a moisture environment substantially surrounding the entire food product during its baking. Such an oven permits baking food products, in particular dough products, and even more particular bagel products, by a convective heat transfer mechanism that provides for quicker and more even cooking of the food product while providing for the making of whatever level of moisture is desired about the food product for imparting a desirable characteristic to the food product. For bagel products, in particular, desirable surface sheen and texture characteristics can be achieved The present invention is also directed to methods of cooking food products, in particular dough products, and even more particular bagel products, by way of such an oven.

A dough sheet sensor comprises a sensing roller, a pivot, a roller support arm and an adjustable counterweight. The sensing roller is displaceable in a first direction as a function of tension in a dough sheet. The roller support arm supports the sensing roller and is attached to the pivot. The adjustable counterweight is attached to the roller support arm and positioned opposite to the pivot with respect to the sensing roller for counterbalancing the sensing roller and the roller support arm. A non-contact distance sensor is operably coupled to the sensing roller through a measurement gap. The measurement gap has a length that varies with the sensing roller displacement.

The present invention includes a process for separating food particles of different specific gravities. The process includes providing a feedstock of the food particles, providing a feedstock of diatomaceous earth and water having a specific gravity effective for particles to float or sink; adding the slurry and separating the floating food particles from the sinking food particles; dewatering the food particles and collecting the water; extracting the diatomaceous earth from the slurry and re-using the diatomaceous earth in the process.

A method of controlling the weight of cut pieces of dough is disclosed. The method includes determining a target mass loading of a strip of dough, measuring the actual mass loading, comparing the actual and target mass loading values, calculating a calendar roller gap distance which compensates for the rheological properties of the dough and adjusting the gap distance of the last calendar roller pair to equalize the actual and target mass loading values.

A french fry cooking apparatus for deep-frying french fries includes a cooking unit having a plurality of frying baskets. Mounted above the cooking unit is a refrigeration unit which includes a first conveyor upon which a supply of frozen french fries is stored. The first conveyor discharges the fries onto a second conveyor which dispenses a metered quantity of fries to a delivery mechanism. The delivery mechanism includes a shaft and a rotatable directional chute for directing the frozen fries from the second conveyor into any one of the plurality of frying baskets. The frying baskets are pivotally attached to the cooking unit and are each movable by way of a drive unit between a loading/draining position for receiving fries from the chute and for draining oil from deep fried fries, a cooking position for deep frying the fries, and a dump position for discharging the deep fried fries from the frying basket. Deep fried fries are discharged onto a further conveyor which takes the fries to a holding bin. The fries are then distributed from the holding bin to customers as per their orders. Frozen french fries are loaded onto the first conveyor by way of a loading mechanism having a loading bin.

A food depositing apparatus for depositing a semi-solid food product within a fixed area defined by a receptacle includes a depositing mechanism. The depositing mechanism includes an extrusion device having an opening through which semi-solid food product can be fed into the extrusion device. A pressure element coupled to a drive mechanism is configured to extrude the semi-solid food product from the extrusion device through an exit port. A valve located at the exit port is adapted to selectively control the flow of extruded semi-solid food product. An air knife positioned adjacent to the cutoff valve cuts the continuous stream of semi-solid food product into semi-solid food pieces. These pieces are deposited on the receptacle which is positioned on a scale. A control module is coupled to the scale and cutoff valve to control operation of the depositing mechanism. To deposit an amount of semi-solid food product whose total weight is within a preselected target weight range, a first amount of semi-solid food product is deposited on the receptacle and weighed to determine its precise weight. The precise weight is fed to the control module which then actuates the depositing mechanism for a second time if necessary to deposit a second amount of semi-solid food product on the receptacle. The total weight of the first and second amounts falls within .+-.10% of a desired target weight.
