The present invention relates to a cylindrical tank for thermal processing of food mixtures, and also to machines for the manufacture of food mixtures, provided such cylindrical tank.

The scope of the invention covers a machine for the manufacture of food mixtures (such as ice cream, creams for confectionery, chocolate products, cooking etc), subjected to single or combined heat treatment (for example, cooling in the case of manufacturing of ice cream or warming and cooling in the case of manufacturing cream pastry) in a cylindrical tank (hereinafter called "cylinder"), accompanied by an appropriate mixer or agitator, which rotate around the longitudinal axis. Control of the temperature of the mixture is carried out using a cooling/heating systems, usually consisting of a coil located on the outer surface of the cylinder.

To determine the temperature of the mixture of the food product within the cylinder, the latter contains a temperature sensor, which are structurally normally mounted on the vertical rear wall forming the bottom of the cylinder, located essentially horizontal (horizontal axis).

The main drawback of this known construction is associated with t is m, the stirrer at a rotation moves the food mass to the front of the cylinder. In this case, in particular when processing a small quantity of the product, the sensor located on the outer cylinder wall is not covered by the product, i.e. it is not in contact with the mixture, resulting in the sensor readings will not match the actual temperature of the mixture.

The main aim of the invention is the creation of a new cylinder for thermal processing of food mixture, which, in contrast to the known cylinder provided with means enabling the determination of the actual temperature of the mixture.

Another objective of the invention is to provide a cylinder of the specified type, which allows to determine the temperature of the food mixture, regardless of its consistency (with more or less fluid), and the number of the mixture inside the cylinder.

Another aim of the invention is to provide a cylinder of the specified type, the design of which there are no obstacles to the normal process of thermal processing of food mixtures and which at the same time allows to determine the instantaneous value of the true temperature in the cylinder of the food mixture.

This and other objectives are achieved by using a cylindrical tank and machine for the manufacture of food mixtures, in accordance with paragraphs 1 and 13 of the formula image is the shadow. Preferred embodiments of the invention are specified in the remaining claims.

The advantage of machines for processing edible mixtures made according to the invention, in comparison with the known machines is that due to the location of the sensor in the front of the cylinder (i.e. where unloaded the food mixture), guaranteed permanent contact of the sensor with the food mixture, which allows to determine the true temperature of the food product located in the cylinder.

This result is also achieved in the case of a small amount of the food mixture in the cylinder, in contrast to the known machines of this type, where the sensor is mounted on the rear of the cylinder, inevitably will not be covered food product.

In addition, when installing the sensor in the front of the cylinder, in combination with its placement on the ring, holding the coil to the body of the cylinder, the sensor is isolated from the cooling/heating device, which otherwise could affect the operation of the sensor. At the same time, the specified location of the sensor does not reduce the efficiency of heating or cooling in the front of the cylinder.

These and other objectives, advantages and features of the invention will become apparent from the description of the preferred options for performing cylinder and machine according to the invention, given by way of example, non-limiting scope of the invention. In the description with references to the drawings, in which:

1 and 2 depict a longitudinal section of a known cylinder for thermal processing of food mixture, with a full load and partial loads, respectively,

figure 3 depicts a longitudinal section of a cylinder according to the first variant of the invention,

4 and 5 depict a perspective view of the cylinder according to the invention with exterior insulation and without it, respectively,

6 depicts a cylinder, shown in figure 3, front partial placket,

7 depicts a longitudinal section of a cylinder according to another variant embodiment of the invention, and

Fig and 9 depict graphs of the temperature of the food mass is processed in the cylinder, shown in Fig.7, from the time when full and partial loading of the tank, respectively.

Figure 1 shows a known cylinder 1. On the back or bottom 3 of the cylinder 1 includes a probe 2 temperature. On the outer surface of the cylinder 1 is located a coil 5 for circulation of cooling or heating medium. In addition, the cylinder 1 is equipped with a front holding ring 1 mounted on the coil 5, an internal mixer or agitator 6, rotating around the axis, and the front flap or flange 7.

Figure 1 in the cylinder 1 is the maximum number of food product 8 (usually corresponding sexes is not the volume of the cylinder 1), and in the cylinder 1 figure 2 - a small amount. When the cylinder is the maximum number of food product 8 (1), sensor 2 temperature immersed in it, and with a small amount of product (see figure 2) sensor 2 is fully open, and his testimony will be consistent with the ambient temperature and not the temperature of the product to be processed in the cylinder 1. Therefore, the processed food product located at the discharge opening of the cylinder shown in figure 2, does not reach a specified state (stability, consistency of cream, and the ability to be smeared and so on)corresponding to its desirable consumer properties.

To eliminate this disadvantage it is proposed the cylinder 1, shown in figure 3, which contains the temperature sensor 9 installed in its front part, in particular in the area 10 of the front part of the casing 4 of the cylinder 1. This area width of about 10 cm starts from the outer edge of the cylinder, i.e., from the discharge flange 7 is used to output the final product from the cylinder 1, or in the vicinity of the flange 7.

Installation of the sensor 9 near the area 10 of the cylinder 1 occupied by the turns of the coil 5, could disturb the equilibrium of the system of heat treatment of the mixture of the food product 8. For example, if the sensor had to remove a certain number of turns, the effect of thermal treatment is ODI would be considerably less especially in the most critical areas of the cylinder, i.e. in the area of discharge of the product. If you install the sensor directly between the turns of the coil, it will be worse to work because of the inevitable impact of a significant temperature gradient when the machine is in operation.

For this reason, the author decided to install the front sensor 9 on the body of the cylinder 1, it secured at the discharge side of the cylinder, essentially coinciding with the installation area on the cylinder 1 of the front ring 11. The region 10 of the shell 4 has a hole 20 for receiving a front sensor 9 into contact with the cylinder 1 product (figure 5).

On the part of the ring 11, the corresponding hole 20 in the cylinder 1, the recess or bend 14 for placement of the sensor 9 (figure 4). It is also possible to keep the sensor 9 in region 10 of the cylinder 1 in a radial position by means of means of restraint, such as an annular slot 13 or perforated clamp is welded to the casing 4 (not shown).

For optimal thermal insulation of the sensor 9 relative to the coil 5, the sensor is preferably protected by a casing 19 of insulating material (figure 4 and 5).

As clearly seen in Fig.6, the front sensor 9 is located so that it is not inside of the shell 4, so as not to interfere with the rotation of the scraper teeth 12 of the mixer 6. With this goal is through the sensor 9 is placed in the annular slot 13, located on the outer side of the shell 4 (6).

Preferably, the front sensor 9 was slightly below theoretical curve, forming a shell 4 of the cylinder 1 (approximately 0.1 mm in the Central part of the hole 20). In this case, guaranteed by the absence of contact of the sensor 9 with the teeth 12 of the mixer and, in addition, the sensor readings will correspond to the temperature of the product to be processed in the cylinder 1.

As shown in Fig.7, the front flange 7, the closing cylinder 1, comprises a hopper 16 for loading ingredients, which is an alternative to the rear channel 15, intended for submission to be processed product, or used in conjunction with the channel 15 and the opening 17 for discharging the final product from the cylinder 1, small adjustable valve 18 (see also Fig.6). As shown in Fig.7, the sensor 9 is located near the hole 17 in the specified area 10 of the cylinder 1 (Fig 3).

In the presented figure 7 an alternative embodiment of the invention the cylinder 1 in front of the temperature sensor 9 has a rear sensor 2 temperature.

While working in the cylinder 1 download product 8, for example through the channel 15, which ends at the bottom of the cylinder 1. The amount of product 8 can vary from full load (corresponding to half of theoretical capacity of the cylinder) to partial load (the leaving less than a quarter of theoretical capacity of the cylinder 1).

When fully loaded cylinder 1 sensor 2 and 9 are in direct contact with the food mixture, i.e. they are fully immersed in it during the whole working cycle. In this case, the temperature values determined by the sensors 2 and 9, are almost the same. In the illustrated example, where the product is a mixture of ice cream, the difference of the readings of the sensors minimum for temperatures below zero (Fig).

In the case of a partial load of the cylinder 1 in contact with the product is only the front sensor 9, which corresponds to figure 9. At temperatures below 0C the difference of the readings of the sensors 2 and 9, while at full load cylinder, this difference is almost absent. The described embodiments of the invention represented in the drawings do not limit the invention, within the scope of which is defined by the claims, various modifications are possible. For example, you may vary the number, type and location of temperature sensors inside the cylinder 1, but the position of at least one of them in front of the cylinder is required.

The cylinder according to the invention can also be used in horizontal selfcoupling machines and combined machines for pasteurization and whipping food mixtures (e.g., machines, known on the market under the trademark "Tittico" Bravo company Spa).
