(57) Abstract:

Use: in the production of crispy potatoes. The inventive device consists of a deep fryer 1 bath with heating elements, transporting conveyor consisting of two parallel chains 3 with the leading 4 and led 5 stars. Gruzopodyomnih elements of the conveyor are basket 6, made of stainless woven rest of the grid. The device contains a slicer 7, a salt spreader and guides.

The invention relates to food processing and can be used for the production of crispy potatoes, French fries, roasting beets, carrots, onions, zucchini, for frying bakery products (cakes, "wood"), for the production of candied fruit and vegetables.

A device for frying food products containing the oil reservoir, the heating elements and the actuator common features with the proposed device. The oil reservoir is made in the form of a cylindrical drum with caps on the ends.

Nevozmojnosti changes roasting mode, unsuitability for the manufacture of many kinds of products, for example, the crispy potatoes.

A device for frying food products containing the oil reservoir, the heating elements, a conveyor for transporting products and drive common features with the proposed device. Roasting food in this known device is similar in cassettes, which later finished food product is extruded.

The disadvantages of this known device are similar to the low productivity associated with the use of tapes, low reliability associated with the contact of the pipeline with oil, the impossibility of making crispy potatoes and French fries.

The closest technical solution to the invention is a device for frying food products containing the roasting bath with heating elements, transporting conveyor with slave and master asterisks, load-carrying elements in the form of baskets and drive with common features with the proposed device.

The disadvantages of this known device the prototype is the difficulty of changing the mode of operation associated with the need to run PR conveyor device prototype is necessary to use expensive and doskonalenia thyristor speed control of motors.

The technical effect of the invention is the simplification changes the mode of the device and simplification of the drive device.

This technical effect is achieved in that the device containing the roasting bath with heating elements, transporting conveyor leading and driven sprockets, the load-carrying elements in the form of baskets and actuator, includes permanent magnets mounted on one of the sprockets, a reed switch mounted on a bracket near the trajectory of the permanent magnets, the intermediate relay and time relay connected to the power bus through the switch is shunted by a first normally open contact relay, and a common connection point of the reed switch and the time switch is connected to the coil of the relay, the second conclusion which through the normally closed contacts of the time switch is connected to the zero bus, and contacts the intermediate relay included in the circuit for controlling the drive of the container.

This effect is achieved by the fact that the device contains a slicer and additional time relay included in parallel with the main (first) time relay, and the normally open contact of relay is the exercise by the actuator vegetable slicers.

In Fig.1 shows a device for frying food; Fig.2 - section a-a in Fig.1; Fig.3 placement of the permanent magnets and reed switch of Fig.4 block diagram of the drive control device of Fig.5 is a timing diagram of operation of the actuator device.

Device for frying food (Fig.1, 2) consists of a deep fryer 1 bath with heating elements 2, the transporting conveyor consisting of two parallel chains 3 with the leading 4 and led 5 stars. Load-carrying elements of the conveyor are basket 6, made of woven stainless steel mesh. The device contains a slicer 7, the spreader 8 salt (sugar) and the guides 9. The chain links have 3 levers (pushers) 10, through which movement is transmitted from the circuit 3 to 6 baskets. Basket 6 related guides 9 and the conveyor chain 3. The suspensions 11 baskets 6 are axis 12 with rollers 13. Axis 12 passing through openings in the levers 10, the rollers 13 are located on the guides 9. The conveyor 3 and the slicer 7 have individual drives (Fig.2 shows the conveyor drive 14). The salt spreader (sugar) 8 can have an individual drive 15 or by means of a belt to connect to the actuator 14 env using the reed switch 16 and the permanent magnets 17 (Fig.3). On one of the sprockets, for example, 4 stars, established the permanent magnets 17, near the trajectory of the permanent magnets 17 on the bracket 18 mounted reed switch 16. Diagram of the drive control device (Fig.4) contains an intermediate relay 19 with normally open contacts 20 and 21 and a group of switching contacts 22, the first time relay 23 with the normally closed contact 24 and the second time relay 25 with a group of switching contacts 26.

The first 23 and second 25 time relay connected between the power bus 27 and zero bus through the switch 16 and parallel connected normally open contact 20 of the relay, which is enabled through the normally closed contacts 24 of the first relay time 23 between zero bus and a common connection point of the reed switch 16 and the time relay 23 and 25.

Change-over contact contact group 22 intermediate relay 19 neutral earthing, and the contacts 28 and 29 of the contact group 22 included in the control circuit of the conveyor drive (for example, the contacts 28 and 29 continuum buttons START and STOP the conveyor).

Normally open contact 21 connected between the zero bus and relay contact contact group 26 time relay 25, contacts 30 and 31 which are included in the control circuit when the>The control circuit drives in Fig.4. In the initial state, the switch 16 is open, the relay 19, 23, 26 and 25 is de-energized. The contact 28 through the contact group 22 neutral earthing, bypasses the START button of the conveyor, the conveyor moves. The slicer is disabled.

One installed on the sprocket permanent magnets 17 is combined with the reed switch 16, causing the reed switch 16 is closed (Fig.5,a), thus it is included under voltage relay 19 and the time relay 23 and 25. Normally open contact 20 of the relay 19 operates a self-locking relay 19. Time relay 23 and 25 begin to count the time intervals T1 and T2. When switching on the relay 19 closes the normally open contact 21 and the switch contact 22, resulting in the conveyor drive is switched off, the conveyor stops and the actuator vegetable slicers is included (Fig.5,b,C).

After the time T2 is triggered a second time relay 25 is switched to its contact 26, causing the actuator vegetable slicers off. At time T2 the slicer 7 cut the required amount of the potato filling one basket pipeline.

After the time T1 is triggered the first time relay 23, the normally closed contacts 24 are opened, the relay 19 is de-energized, its contacts 20 22 Perek is no 23 and 25 remain enabled, the contacts 24 remain open and do not allow to re-enter the relay 19. In the initial stage of movement of the sprocket 4, the reed switch 16 is open, the time relay 23 and 25 is de-energized, the circuit of Fig.4 passes to its original state.

The movement of the conveyor from one to another circuit of the reed switch 16 occurs at the time T3. The time T3 is not adjustable and is determined by the speed of movement of the conveyor. At time T3, one of the baskets (with a finished product) out of the frying bath, and one basket (with raw sliced potatoes) is included in the frying bath.

Thus, T1 is the time interval the stationary state of the pipeline, T2 interval time vegetable slicers; T3 time interval of movement of the conveyor from one to another stationary state, and T3 << T1; the number of baskets being simultaneously in the frying bath.

Based on these designations, the time of frying is TJ KT1.

If time frying TJ set, the time interval T1 is set on the time switch 23, is defined as T1 TJ/K

Technical advantages of the proposed device compared to a device prototype, which is implemented at a very slow continuous and controlled movement of the conveyor, allemani on time relay 23 of the conveyor,

to simplify the design of the actuator, due to the fact that the speed of the conveyor 3 is not regulated and, therefore, no need to use complicated thyristor converters, as well as the reduction ratio of reduction gear conveyor and the associated simplification of the gearbox.
