Description

Technical field

The invention relates to the food industry, as well as to machine tools for such an industry, and can be used both in the manufacture of machines for baking pancakes (for example, carousel type), and for such baking itself.

State of the art

Known wooden stick for leveling a portion of pancake dough on a frying surface (http://www.trapeza.ru/goods/57113/).

It is certainly convenient, but does not allow leveling in automatic mode.

Also known is a device for leveling on a frying surface of a fluid such as oil (htpp: //www.krepelek.com/crepiere-professionnelle/machine-de-cuisson.php).

This device is selected as a prototype.

The prototype includes a nozzle that provides a portion of oil to the said surface, as well as at least one blade rotatable around the nozzle, which ensures uniform distribution of the portion over the said surface due to its rotation relative to the said surface during contact with the oil at its lower edge .

From the point of view of leveling the pancake dough, the prototype has several drawbacks (which are irrelevant in terms of leveling-distribution of oil).

The first should include the absence of supporting elements that accurately determine the positioning of the blades relative to the frying surface (at what height they are from the surface, which at a given portion of the dough will determine the thickness and diameter of the pancake). The problem here is that different stoves or different sections of the whole cooking table of the carousel type machine can be located at different levels.

The second drawback is associated with the orientation on the blades of a flexible material, which is well impregnated with oil. Such blades are well wetted with dough. Dough sticks to them. When lifting the blades, drops of dough break down on a pancake. Damn turns ugly. The stiffness of the blade is also important - the blade should not bend.

Technical result

The objective of the invention is the creation of a high-performance leveling device for a portion of pancake dough on a frying surface for the manufacture of pancakes of a given thickness and diameter.

The technical result achieved by the implementation of the distinguishing features of the invention, in the manufacture of pancakes is:

- almost completely eliminating the defect in appearance, which is achieved by ensuring accurate positioning of the blades relative to the frying surface, and also by quickly removing the dough from the blades during their lifting;

- to reduce the time for reconfiguring the machine to make pancakes with other parameters (thickness, diameter) through the use of an easily accessible easy-to-use adjustment unit, as well as a slider;

- in reducing the setup time of the machine (from the point of view of alignment horizontality of the lower edge of the blade).

Information about the possibility of implementing the invention

A portion leveler (including one made up of several separate smaller portion sizes) of the fluid on the frying surface, designed to level at least one portion of pancake dough on the surface, can be arranged as follows.

It should include a nozzle 14, which provides a single portion (from which a separate pancake will subsequently be obtained) to be supplied to the surface.

In addition, it should include at least one blade 13 that is rotatable around the nozzle 13, which ensures uniform distribution of a single portion over said surface due to the rotation of the blade relative to the said surface during contact with the dough with its lower edge 11.

In this case, the leveler must include at least one support roller 10, more remote from the nozzle than the blade, which is designed to abut against said surface.

The roller relative to the blade is installed in such a way that it sets the position of the blade relative to the frying surface.

To configure the leveler for the release of pancakes of different thicknesses, at least one regulating unit is included in it, which ensures the setting of the required position of the blade relative to the roller, which determines the height of the blade above the mentioned surface in contact with the last roller.

Such a unit includes a movement mechanism relative to the nozzle of the blade or roller and a mechanism for fixing their relative position.

The roller and the blade are mechanically connected to the pulley 4, which provides (periodic) rotation of the latter.

The device may include two or more rollers, as well as two or more blades.

The control unit may include a movement mechanism relative to the blade nozzle, while such a mechanism may include at least two spaced apart independently adjustable in height using a threaded connection of the blade holder 16, which makes it possible to adjust the horizontality of the lower edge of the last 12.

A lock nut 15 can be used to lock the holder in position.

The screed can include independent movement mechanisms relative to the nozzle of each of the blades, despite the fact that such mechanisms can include at least two spaced apart independently adjustable in height using a threaded connection of the blade holder.

The control unit may include mechanisms of movement relative to the nozzle of the entire group of rollers surrounding it, for which it includes a nut to which the roller holders are rigidly attached (such as holder 9), as well as a lock nut 6 with a “wing” bracket 17, which provides for locking the nut with roller holders for parts with an external threaded surface 8.

The screed can simultaneously include two control nodes, the first of which allows you to change the position relative to the nozzle of the blades, and the second of the rollers.

The adjustment task is to change the relative position of the lower part of the roller and the lower edge of the blade.

The nozzle through the adapter tube 2 can be connected to the fitting 1, designed to connect to it a pipe through which the dough is fed, while the adapter tube can be connected to the pulley using at least one rolling bearing 3 (preferably using a pair of spaced bearings )

The blades with respect to the nozzle can be installed radially and / or at an acute angle to the mentioned surface in the direction of their rotation - the dough coming out from under the blades should form an obtuse angle with its rear surface.

A good result is achieved when using curved blades, the lower edge of which is spiral.

The blade can be made of metal, and it can be a plate, at least the lower edge of which is polished.

An electric vibrator can be mounted on the blade, designed to transmit vibration to the blade itself in order to increase the fluidity of the dough with which the blade is in contact or that has adhered to the blade. The task of the vibrator is to eliminate the formation of droplets of dough when lifting the movable part of the leveler and moving the frying surface.

The vibrator may have autonomous power supply - accumulator / battery located in the upper or middle part of the blade in a sealed enclosure.

Additionally, the vibrator may have an accelerometer that activates the vibrator when lifting the blade.

An ultrasonic vibrator based on a piezoelectric transducer can be mounted on the blade.

The blade can be made in the form of an ultrasound concentrator on the lower edge of the blade, for which it can have a prismatic shape with a narrowing to the lower edge of the blade.

The lower edge of the blade on its peripheral part - on the part remote from the nozzle - may have a protrusion designed to limit the spread of the test for it (for the protrusion), as a result of which the lower edge of the scapula can be made with a step.

The protrusion on the lower edge of the blade can be made in the form of a slider, which can be moved along the edge of the blade to the nozzle or from the nozzle when setting up the machine to change the diameter of the pancakes made for this, the blade can have guides and a stopper to fix the specified position of the slider.

Either the rollers can be spring-loaded relative to the vanes, or the rollers with vanes can be spring-loaded relative to the pulley.

So, the pulley can be tightened onto the adapter 5 with the bearing 3.

In the lower part, a cylinder with a flange can be rigidly attached to the adapter, to which the guides for the springs 7 can be welded.

The springs can rest in the glass 8, and the guides can be fixed with a screw (with a round head of Fig. 1 on the left).

As a result, the pulley and nozzle are spring-loaded relative to the block of rollers and blades.

The screed can include several pulleys and nozzles, as well as several groups of blades and rollers that surround each of its nozzles and are driven in rotation due to the presence of its own pulley (Fig. 3, 4, 5).

So, it can include three pulleys and 3 nozzles, as well as 3 groups of blades and 3 groups of rollers that surround each nozzle and are driven by its own pulley.

The pulleys can be connected by a belt 18 to each other and to the engine 19.

The screed may include a housing 20, relative to which the rotation of the roller and the blade occurs, while the housing can be made with the possibility of its attachment to the device, providing translational movement up and down, for which it may include connecting and / or landing elements 21.

From above, a pneumatic or hydro or hydropneumatic cylinder 25 can be attached to the device, the upper part of which can be rigidly attached to the stationary test supply unit 23, so that when the cylinder is triggered, the movable part of the device will be lowered until the rollers come in contact with the surface or its rise above this surface during the transition (automatic) to leveling the dough at another place on the surface or on other stoves.

The test supply unit may include bodies 2 6 for adjusting the portion size of the latter, the number of which should be equal to the number of nozzles.

The screed can be configured to independently supply dough to the nozzles of each nozzle, for which it can include independent containers for forming portions of dough, for example, independent pistons 22 controlled by panel 24.

To simplify the maintenance of the leveler, the rollers can be fitted using plain bearings.

Best leveler implementation

The best version of the leveler design is shown in the figures shown as illustrations.

Leveling operation

Presented in FIG. 3-5, the leveling device performs three functions - it doses three single portions of the dough installed by volume controllers 26, at the same time unloads them on the frying surface and carries out the leveling of the dough in three places simultaneously.

The dough enters the leveler from an external container connected to it by a pipeline.

The pistons are connected by a pipeline (not shown in FIG. 5) each with its own fitting.

After proper heating of the frying table has been carried out, the pneumatic cylinder 25 is activated and the movable part of the leveler lowers to the table until the rollers stop on the frying surface.

From the nozzle the dough is fed, which spreads over the frying surface, which is facilitated by the rotation of the blade carried out at the time of feeding the dough.

Leveling the dough on the frying surface is carried out.

After leveling the test, the movable part of the leveler rises.

The cooking table rotates and under the leveler is free of dough portion of the cooking surface. The cycle repeats.

To quickly adjust the thickness of the pancake, the rollers are raised or lowered.

To do this, raise the wing nut (screw) and turn the nut to which the roller holders are attached (for example, to which are welded). After they lock the nut mentioned last, pulling the wing-lock nut to it.

If additional adjustment of the position of the blades relative to the frying surface is required, a node for adjusting the position of the blades relative to the nozzle is used.

To do this, unscrew the corresponding locknuts and screw or unscrew the blade holders.

The horizontalness of the lower edge of the blades is checked with a stylus.

The relationship of distinctive features with the claimed technical result

EFFECT: invention makes it possible to produce high-performance pancake dough levelers on a frying surface for making pancakes of a given thickness and diameter.

The accuracy of positioning the blades relative to the frying surface is achieved through the use of rollers and the above-described adjustment units.

Reducing the time for reconfiguring the machine to make pancakes with new parameters is ensured by using an easily accessible adjustment unit in accordance with the design presented.
