Detailed Description

The following describes specific embodiments of the present utility model in detail with reference to the drawings. It should be understood that the detailed description and specific examples, while indicating and illustrating the utility model, are not intended to limit the utility model.

For a better understanding of the feeding apparatus of the present utility model, the general flow of cheese production will first be briefly described before a specific description of the feeding apparatus. As previously mentioned, in the industrial cheese making process, it is necessary to mix powdered raw materials such as casein powder with other cheese raw materials in other forms such as cream and agitate the mixture to form a curd; heating and stretching the coagulated cheese in a melting and stretching pot to enable the coagulated cheese to have better stretchability; cooling, cutting, shaping, and packaging. In this process, the degree of mixing of the cheese raw materials has a significant impact on the quality of the final formed cheese product.

To this end, the present utility model provides a feeding apparatus 10 for cheese production, as shown in FIG. 1. The feeder apparatus 10 has a feed port 14, a discharge port 19, and a vibratory screening mechanism disposed between the feed port 14 and the discharge port 19. Thus, the powdery raw material such as casein powder can be fed into the feeding apparatus through the feeding port 14, and after passing through the vibration screening mechanism, it is discharged through the discharging port 19 to be fed into the subsequent stirring, stretching and other processes.

In particular, the vibratory screening mechanism comprises a screen 16 and a vibratory drive 17, e.g. a motor. The screen 16 is arranged in the material flow path from the feed opening 14 to the discharge opening 19 and can be driven to vibrate by a vibration driving device 17, so that the powdery cheese raw material from the feed opening 14 is filtered by the screen 16, only powder meeting the particle size requirement is allowed to be output from the discharge opening 19 into the subsequent process, and lumps such as caking, sundries and the like are blocked. In this process, the agglomerates formed by the agglomeration of the powdered cheese material are broken up during the vibration of the screen 16, achieving a uniform dispersion of the powdered material, avoiding the adverse effects of the agglomeration of the powdered material on the solubility and product hydration during subsequent processes.

Therefore, the feeding equipment can remove the lump matters in the powdery cheese raw materials by utilizing the vibration screening mechanism, so that the feeding equipment has larger contact area when being mixed with other cheese raw materials, has good solubility and hydration, and is favorable for fully and uniformly mixing with other cheese raw materials such as cream in the subsequent working procedure so as to produce cheese products with stable and uniform quality.

In order to effectively break up the caking in the powdered cheese material, the vibration frequency of the screen 19 should not be too low. In a preferred embodiment of the utility model, the vibration drive 19 may be mounted on the outer housing and drivingly connected to the screen 19 by a suitable transmission such that the screen 19 has a vibration frequency of 1000-2000 times/minute. For example, the vibration frequency may be 1460 times/min, thereby effectively crushing the agglomerates formed by the coagulation of the powdered material.

In addition, the particle size of the powdered cheese material has an important effect on solubility and product hydration, and the mesh size of the screen 19 should not be too large. In a preferred embodiment, the mesh size data may be 50-100 mesh to allow smooth passage of the powdered casein size material and to prevent caking into the mixer. Meanwhile, the vibration screening mechanism can also screen out sundries such as plastic fragments and the like accidentally falling into the powdery raw materials, so that the edible safety of the prepared cheese product is ensured.

The powdery raw materials easily generate dust in the process of being put into the feeding equipment 10 and when being subjected to vibration screening by the vibration screening mechanism, are unfavorable for the health of operators, and are easy to cause accidents such as dust explosion. For this purpose, a dust removal fan 11 may be provided at the top of the feeding apparatus 10, in order to avoid accumulation of excessive dust in the inner cavity of the feeding apparatus 10. The dust removal fan 11 may be arranged at other suitable positions as long as it can reduce dust in the inner cavity of the feeding device 10. In a preferred embodiment, the dust removal fan 11 is mounted near the feed opening 14 to reduce the direct spread of dust through the feed opening 14 to the operator. For example, in the case of the illustrated arrangement of the feed opening 14 at the top side of the feeding device 10, the dust removing fan 11 is installed at the top of the feeding device 10, so that dust can be timely removed immediately after the powder cheese raw material is fed and is vibrated and sieved. Thus, the feeding device 10 essentially constitutes a dust-free feeding station, which can be applied in cheese production to uniformly disperse powdery raw materials, and effectively improve product quality and operation safety.

In order to facilitate the operator's feeding of the powdered cheese material through the feed opening 14, the feed opening 14 may be provided at the side of the feeding device 10 and extend obliquely with respect to the vertical plane. Thus, the operator does not need to lift the package of material containing the powdered cheese material to a position beyond the overall height of the feeding apparatus 10 to perform feeding relatively easily. On the basis, a feeding platform 13 can be arranged at the lower edge of the feeding opening 14, and when operators feed, the powdery cheese raw materials can be lifted and placed on the feeding platform 13 at first, so that the raw materials can be fed according to the requirement. Here, the feeding platform 13 may extend horizontally outward with respect to the feeding port 14.

As previously described, dust generated during vibratory screening may be outwardly dispersed through the feed inlet 14, which is detrimental to the health of the operator. For this purpose, a feed opening cover 15 can be provided in order to close the feed opening 14 when required. The access cover 15 may be provided in a number of suitable forms, for example, in the illustrated preferred embodiment the access cover 15 is pivotally mounted to the housing of the feeding device 10 and is pivotable between a position closing and opening the access opening 14. The material inlet cover 15 can be pivotally connected to the edge of the material inlet 14, and can be turned up and down or left and right relative to the material inlet 14 to close or open the material inlet 14.

During the feeding operation, the feeding port cover 15 may be kept in a position to open the feeding port 14 for a single person to operate. For this purpose, a pneumatic support rod 18 can be connected between the feed flap 15 and the housing of the feed device 10, which pneumatic support rod 18 can be extended and retracted in order to hold the feed flap 15 in the open position in the extended state.

After sieving, the powdered raw material is mixed with other cheese raw materials by entering a mixer, which may be located below the feeding device 10. To facilitate the accumulation of the sieved powdery raw material into the stirring chamber of the stirring machine, a conical silo 12 may be provided at the bottom of the stirring device 10, which conical silo 12 may have a downward discharge opening 19.

In another aspect, the utility model also provides a cheese production line comprising the feeding device, and the production method comprises the following steps: s1, putting powdery cheese raw materials (such as skim milk powder, casein powder and the like) into the feeding equipment so as to remove lumps therein, wherein the crushing of raw material caking and the filtering of sundries such as plastic fragments and the like are included; s2, mixing the powdery cheese raw material from which the cake is removed with other cheese raw materials (such as butter, water and the like), wherein the mixture can be stirred and tumbled in the process; s3, heating and stirring (stretching) the mixed cheese raw materials in a scalding stretching device such as a melting stretching pot to form block cheese; s4, cutting and forming the block cheese into shapes suitable for packaging and transportation, such as sheets, strips or sections.

Therefore, the cheese production method disclosed by the utility model utilizes the vibration screening mechanism in the feeding equipment to remove raw material caking, can ensure good solubility and product hydratability, and is beneficial to producing cheese products with stable and uniform quality.

The preferred embodiments of the present utility model have been described in detail above with reference to the accompanying drawings, but the present utility model is not limited thereto.
