Description

Technical Field

[0001] The invention relates to the technical field of meat product fermentation and enzymolysis, and in particular provides a meat product fermentation and enzymolysis device and an enzymolysis method thereof. Background Art

[0002] At present, with the continuous improvement of living standards, people pay more and more attention to the safety, flavor and nutritional value of food. Meat jerky made by enzymatic fermentation process uses specific enzyme preparations to decompose the original protein of meat to a limited extent, generate peptides and amino acid molecules, improve the texture and taste of meat, maximize intestinal absorption and utilization, meet the daily nutritional supplement needs, and are becoming more and more popular among people.

[0003] Meat jerky produced by enzymatic hydrolysis and fermentation is generally made from pork or beef. During the fermentation and enzymatic hydrolysis process of the enzymatic meat, the quality of the enzymatic meat is affected by factors such as the amount of enzyme added, the uniformity of mixing the ingredients containing the enzyme and the meat, and the temperature.

[0004] At present, fermentation enzymolysis devices mostly use single-chamber enzymolysis containers for stirring and mixing. A single stirring chamber and stirring paddle are set in the stirring container. Generally, after the meat material is placed in the container, the ingredients are added on the upper surface at one time. During the stirring process, the meat material cannot be reciprocated as a whole, and only the meat material around the stirring paddle is fully stirred. The meat material at the bottom corners of the single-chamber enzymolysis container is difficult to enter the stirring center and cannot be fully stirred, making it difficult to stir the meat material as a whole. It is easy to cause the problem of uneven stirring of the meat material and the ingredients containing enzyme preparations, further affecting the product quality of the enzymolysis meat. In addition, only a stirring paddle is set in the current single enzymolysis container, which can only stir and mix the meat material, and cannot play the role of rolling and crushing the meat material. Research and production time show that during the stirring and mixing process, rolling and crushing the meat material can increase the viscosity of the meat material and increase the toughness and taste of the prepared meat jerky. Therefore, it is necessary to improve the corresponding equipment to improve product quality. At the same time, in order to adjust the temperature inside the enzymatic hydrolysis container, current enzymatic hydrolysis containers mostly use heating and heat preservation components installed on the wall of the enzymatic hydrolysis container. When the volume of the internal meat material is large, the process of heat conduction from the heating and heat preservation components of the wall to the center of the meat material takes a long time, and the temperature adjustment speed is slow, which affects the efficiency of fermentation enzymatic hydrolysis and is not suitable for use in mass production processes.

[0021] Most of the current fermentation and enzymolysis devices use a single-chamber enzymolysis container for stirring and mixing. A single stirring chamber and stirring paddle are set in the stirring container, and the meat material cannot be reciprocated as a whole, resulting in uneven stirring of the meat material as a whole and uneven stirring of the meat material and the ingredients, which affects the uniformity of the enzymolysis meat. In addition, stirring and mixing cannot roll and crush the meat material, the viscosity of the meat material cannot be improved, and the toughness and taste of the prepared meat jerky are poor. The process of heat conduction from the heating and insulation components of the wall to the center of the meat material takes a long time, and the temperature adjustment speed is slow, which affects the efficiency of fermentation and enzymolysis, and is not suitable for use in mass production processes.

In the stirring and mixing process, the overall circulation mixing of the meat material is realized, and the ingredients containing the enzyme preparation are evenly added in the circulation mixing process, so as to realize the rolling and crushing of the meat material, so as to improve the mixing uniformity between the meat materials and between the meat materials and the ingredients containing the enzyme preparation in the fermentation enzymolysis process, and effectively improve the taste quality such as the uniformity and toughness of the enzymolysis meat.

[0028] Furthermore, the outer part of the core barrel 2 is staggered with outer spiral blades 23 and rolling wheels 24 along the circumferential direction.

In the annular cavity 11, the core tube 2 drives the rolling wheel 24 to cooperate with the inner wall of the outer tube 1 to roll the meat to increase the viscosity, driving the outer spiral blade 23 to scrape the meat adhering to the inner wall of the outer tube 1 and drive the meat downward; S40. When the meat passes through the bottom of the central cavity 21 and the annular cavity 11, the core barrel 2 drives the movable rolling teeth 25 to rotate relative to the fixed rolling teeth 13 to roll the meat to increase the viscosity; S50. The enzymolysis time is generally about 3-4 hours, which can be adjusted according to different products and the degree of enzymolysis.

[0033] Embodiment 3 On the basis of the first and second embodiments, the structure of the provided meat product fermentation and enzymolysis device is further optimized to realize the functions of heating and heating the meat and keeping it warm separately, thereby improving the heating efficiency and the temperature control accuracy of the insulation. like Fig. 9 As shown, in some preferred embodiments, the meat product fermentation and enzymatic hydrolysis device is also provided with a heating and heat preservation unit, and the heating and heat preservation unit includes a first electric heating plate 53 and a second electric heating plate 54, the first electric heating plate 53 is arranged in each inner spiral blade of the circulating stirring paddle 3, and the power line connected to the first electric heating plate 53 passes through the central rotating shaft and is connected to the power supply through an electric slip ring; the second electric heating plate 54 is arranged in a surrounding manner in the cylinder wall of the outer cylinder 1, and the power supply is connected to the second electric heating plate 54 through another power line.
