Description

The utility model relates to the field of food industry, in particular to frying devices and can be used for deep-frying donuts.

A device for deep-frying food products containing a deep-frying bath, a dispenser of the initial product, a frying chamber, a heater for heating the deep-frying in the bath, a window for loading the initial product, elements for moving the fried product and means for replenishing the deep-frying (RF patent No. 2129831 for C. A47J 37/12 dated 05/10/1999).

The disadvantage of this device is the relatively low quality of the products and the low operational ability of the device.

Also known is a device for frying donuts in deep fat, containing a hopper for dough, a hopper for forming dough pieces, a mechanism for moving the blanks and a heat-insulating deep-frying bath with heaters (RF patent No. 2165231 on A47J 37/12 of 04/20/2001). The disadvantage of this device is the relatively low quality of the donuts, due to insufficient circulation of deep fat and uneven frying mode of the whole volume of donuts.

The closest technical solution for the combination of essential features is a device for deep-frying food products containing a dispenser for piece semi-finished products, a U-shaped deep-frying chamber, a preliminary frying chamber, a heater, a product transfer unit with a lifting element in the deep-frying chamber and in the receiving tray, capacity for excess deep fat and preliminary frying capacity (utility model No. 163869 according to class A47J 37/12 of 08/10/2016)

The disadvantage of this device is the low quality of the finished product, insufficient operational reliability of the device and the performance of the device.

The disadvantages of this device are due to the fact that the preliminary frying tank is removable and the joint between the specified container and the deep-frying chamber is not tight, which leads to the deep-frying chamber splashing out when the donut is immersed in oil, which, firstly, increases its consumption, and, secondly, the deep fat fryer begins to smoke, which can lead to its ignition.

In addition, when moving a donut into the deep-frying chamber, a change in the shape of the donut takes place, its marketability is lost, and in some cases the position of the donuts can lead to a stop of the entire product movement system.

The problem, which the utility model is aimed at, is to improve the quality of the finished product, operational reliability, productivity and economic efficiency of the device.

The problem is solved due to the fact that the device for frying donuts in deep fat, containing a dosing unit, is equipped with a refrigerated storage chamber for dough, with a unit for moving the product, a preliminary frying chamber, a deep-frying chamber in a U-shape, a unit for moving the product along the deep-frying chamber using a conveyor , the unit for moving the product in the preliminary frying chamber is equipped with a carousel with displacement cells with the possibility of moving the product in the plane of capture of the product by the unit for moving along the deep-frying chamber, the unit is ne the movements in the deep-frying chamber are equipped with donut substrates and a donut pick-up element, while in the lower part of the deep-frying chamber there is a container for collecting dough pieces and removing oil through a drain valve, and between the vertical elements of the deep-frying chamber there is a tube for draining excess deep-fat into a container with a coarse filter cleaning connected to the pre-fry tank through the pump.

In FIG. 1 - presents a General view of a device for frying donuts in deep fat.

In FIG. 2 is a front view of a deep-fat donut fryer.

In FIG. 3 is a side view of a deep-fried donut fryer.

The device for frying donuts in deep fat, contains a refrigerating chamber for storing dough 1, a dosing unit 2 a container 3 for storing dough, a preliminary frying chamber 4, a deep-frying chamber U-shaped 5, a stepping motor 6, a displacement unit 7, the preliminary frying chamber is equipped with a carousel 8, on which cells 9 are driven, driven by a stepper motor 10, the product is moved in the deep-frying chamber by a conveyor 11 provided with a substrate 12 for placing a donut on it and an element 13 for removing the donut. In the lower part of the deep-frying chamber 5 there is a container 14 for collecting pieces of dough and draining oil through a drain valve 15. Between the vertical elements of the deep-frying chamber there is a tube for draining excess deep-frying into a temporary storage tank 16, connected to the preliminary frying chamber 4 through a pump 17. The device is equipped with capacity 18 for storing the finished product. The temporary storage capacity of the deep-fat fryer is equipped with a coarse filter 19, and ring heating elements 20 are placed on the case of the deep-frying chamber 5.

A device for frying donuts in deep fat works as follows.

After loading the container 3 with the dough into the refrigerating chamber 1, turning on the device and warming it up (the switching elements are not shown conditionally) the device starts to work. The dosing unit 2 with the container 3 with the dough fixed on it starts moving to the pre-frying chamber 4 with the help of the displacement unit 7 and, having reached the set position, stops and the donut is transferred to the cell 9, the cells 9 are moved in the pre-frying bath using the carousel 8 driven into motion by a stepper motor 10. After filling all the cells with donuts, the conveyor 11 continues to move, and the donut substrate 12 immerses the donut below the plane of rotation of the carousel 8 and the conveyor 11 stops. Next, the carousel 8 moves the cell 9 to the next position, placing another donut to be picked up by the substrate 12, the cycles are repeated until the substrate 12 pushes the donut onto the element for removing the donut 13 and then turning the donut over and putting it into the storage container 18 product.

When the donuts are submerged, the preliminary frying chamber has excessive oil displacement, which goes into the temporary storage tank 16. Together with excess oil, pieces of dough are washed out, which can appear when the donut is transferred to cells 9. The coarse filter 19 delays the pieces of dough, and the oil is pumped back into the preliminary frying chamber 4 using the pump 17.

The implementation of the product transfer unit in the preliminary frying chamber with a carousel with movement cells in the product capture plane, the movement unit along the deep-frying chamber, eliminates the change in the geometry of the product and its jam when moving from the preliminary frying bath to the main frying tank. The presence of the temporary storage capacity of the deep fat fryer prevents the frying from spilling out when the donuts are immersed in oil, the coarse filter together with the piece collecting capacity allows to increase the life of the deep fat fryer, the presence of a cooling chamber allows to increase the shelf life of the dough, significantly reducing the waste of the original ingredients, improving the economic performance of the apparatus, and product quality, improve its presentation, increase the frying process productivity.
