RU2269890C1 - Batch-operated butter churn - Google Patents

Abstract

FIELD: butter churn used in milk industry enterprises and farms.

SUBSTANCE: butter churn has immovable cylindrical reservoir with churning mechanism axially arranged within cylindrical reservoir and consisting of two mixers rotating in opposite directions. Mixers are fixed within cone reducer mounted on hollow shaft which rotates in bearing units. Power required for providing necessary rotational frequency is transmitted through V-belt transmission and drive shaft mounted on hollow shaft, said transmission being provided by means of electric engine fixed with its flange on reservoir closure. Viewing window allows churning process to be visually controlled. Reservoir closure is fixed with the help of clamps.

EFFECT: reduced butter churning time and increased efficiency.

Description

The invention relates to devices for producing butter and can be used at dairy enterprises and in farms.

Known oil batch manufacturer (1), brand YAZ-OME-0.13, containing a rotating cylindrical container with four blades. The tank mounted on rolling bearings on the frame of the welded structure has a window for loading raw materials and unloading the finished product, windows for visual monitoring of the process and a crane for draining buttermilk. A drive consisting of an electric motor and gearbox is also installed on the frame rack. Churning cream in the butter manufacturer occurs due to the rotation of a container filled with 25 ... 40% cream.

Known oil batch manufacturer (2) brand MM-1000, containing a container rotating around its own axis, and a drive mechanism mounted in the frame. Four metal blades in the form of a spiral strip are fixed inside the tank. A string passes along the axis of the can. To observe the churning process, two viewing windows are mounted in the bottom. Churning cream in the butter manufacturer is due to the rotation of the tank around its axis.

The disadvantages of these oil producers are the large inertial loads on the support nodes, high energy consumption and the long duration of the oil churning process.

A known batch-type oil manufacturer (3), comprising a paddle whip located in a fixed container, mounted 2 on a shaft provided with a drive handle, which is supported by bearings located in the side walls. The churning of the oil is carried out by rotation of the shaft with the drive handle, on which the blade chipper is fixed, the blades of which carry out the working process of churning the butter from cream. This process lasts 20 ... 30 minutes.

The disadvantage of this oil manufacturer is the long duration of the technological process of churning oil.

A known oil manufacturer of periodic action (4), which contains a fixed cylindrical-shaped container, along the axis of which a mixer is mounted, is mounted on a drive shaft mounted coaxially with the rotor of the electric motor. Fixed beats are installed inside the tank. The mixer has the form of a twin propeller with opposite bending of the blades. The agitator is installed in the lower third of the volume of the product being knocked down. When the shaft rotates, the agitator mounted on it rotates, which drives the whipped product into rotational motion. The disadvantage of such an oil manufacturer is the low productivity, and the fact that the rotation speed of the mixer is strictly defined and disconnection from the specified characteristics will lead to the oil manufacturer working in the mixer mode.

Known oil manufacturer (5), which contains a fixed container, along the axis of which a churning mechanism is installed. The churning mechanism consists of two cones conjugated by one surface with fixed guide vanes. A disadvantage of an oil producer of this type is loss during the extraction of oil grain at low production volumes.

The closest in technical essence to the claimed invention is a batch-type oil producer (6), comprising a housing on which a fixed container with a churning mechanism is mounted, which contains a disk mounted for rotation on a carrier. A carrier mounted on a bearing rotates around a shaft, on the end of which a gear is fixed, which is meshed with the ring gear. When the disk rotates around the axis and around the shaft, centrifugal and axial flows of the mixed product arise, contributing to the formation of oil grains.

The disadvantage of this oil manufacturer is that churning is possible only at high frequencies, the rotation of the shaft, and in the process of oil formation churning mechanism interacts with the product only in a limited area.

The claimed invention is aimed at eliminating the noted drawbacks and from its use the following technical result was obtained: reducing the time of the process of whipping and increasing productivity.

The specified technical result is achieved due to the fact that the proposed periodic manufacturer of oil, containing a container in which a churning mechanism is installed, which differs from the known solutions in that the churning mechanism, consisting of two mixers, performs a complex movement during operation, providing intensive destruction of the shell of fat globules and their aggregation (sticking together), that is, the formation of oil grains.

When carrying out the oil churning process, the distinguishing features identified (churning mechanism made in the form of two mixers making a complex movement) in combination with the known features (fixed tank with churning mechanism) will provide a technical result consisting in reducing the time of the churning process and increasing productivity.

The drawing shows a batch oil producer.

The batch oil producer contains a fixed cylindrical tank 1, the axis of which is equipped with a churning mechanism consisting of two agitators 2, rotating in opposite directions and fixed in a bevel gear 3. The bevel gear 3 is mounted on a hollow shaft 4, which rotates in the bearing units 5 and 6. The power necessary to ensure the required speed through a V-belt transmission 7 and a drive shaft 8 installed in the hollow shaft 4, gives the electric motor 9, mounted by a flange on cr to the tank top 10. For visual monitoring of the knocking down process, there is a viewing window 11. The tank cover 10 is fixed with clamps 12.

Oil manufacturer works as follows.

Cream is poured into a fixed container 1, a lid 10 with a churning mechanism is installed, the clamps 12 are closed. When the drive is turned on, the mixer 2, receiving torque from the drive shaft 8 through a bevel gear 3, creates two counter flows of the processed product due to rotation in opposite directions ( cream). The opposing vortex flows occurring in this case force the hollow shaft 4 with the fixed churning mechanism to perform axial rotation, thereby blocking the previously untreated zones. The churning process can be visually monitored through the viewing window 11. At the end of the process, the clamps 12 open, the lid of the tank 10, with the chipping mechanism fixed in it, is removed and the resulting product is removed.
