Embodiment 1

[0038] Embodiment 1: a kind of donkey hide treatment method and technical process before boiling donkey-hide gelatin, comprising the following steps:

[0039] S1. After the live donkeys are quarantined, they are sent to large slaughterhouses for slaughter. After the live donkeys are slaughtered, they enter a food-grade production and processing environment, and the donkey skins are removed for quarantine;

[0040] S2. Send the donkey skin in S1 to the acid discharge room. First, control the temperature of the acid discharge room at 0-12°C, the wind speed at 1-2m / s, and after the cooling time of 10-16h, adjust the temperature of the acid discharge room to 15-16 ℃, after the suspension time is 30-40h, adjust the temperature of the acid discharge room at 0-5°C, control the relative humidity at 80%-98%, and let the air flow naturally for 30-40h to complete the acid discharge step;

[0041] S3. Put the donkey skin that has completed the acid removal step in S2 on the donkey skin me...

Embodiment 2

[0051] Embodiment 2: Based on Embodiment 1, the difference is that the drying room includes a lighting room A2, a lighting room B6 and a ventilation drying room 9, and the drying room is sequentially provided with a lighting room A2, a lighting room B6 and a ventilation drying room from left to right. Room 9, the left side of lighting room A2 is provided with vent A1, the upper end of lighting room A2 is provided with glass lighting wall 3, the middle of lighting room A2 and lighting room B6 is provided with support column 4, and the top left side of lighting room B6 is provided with glass lighting wall B5, ventilation openings C8 are arranged on the left and right sides of the ventilation drying chamber 9, and six exhaust outlets 7 are uniformly arranged on the top of the ventilation drying chamber 9.

[0052] Air velocity entering vent C8 by temperature difference :

[0054] In the above formula: - the specific gravity of the outside air, - the difference b...

Embodiment 3

[0065] Example 3: Based on Example 1, the difference is that after the live donkey is slaughtered, the donkey skin enters a food-grade production and processing environment and then undergoes acid discharge. The temperature of the acid discharge room is controlled at 8°C, and the wind speed is controlled at 2m / s. After 12 hours, adjust the temperature of the acid discharge room to 15°C. After the suspension time of 30, adjust the temperature of the acid discharge room to 3°C, and control the relative humidity at 88%. After 30 hours of natural air convection, the acid discharge is completed and the next step is to remove the flesh from the fresh skin. It is easier to remove meat and oil from salt-dried skin, and the cleanliness of the treatment is greatly improved, and the use of automatic equipment to remove the fat layer improves work efficiency, and then enters the automatic shaving line to remove the hair on the donkey skin and then enters the automatic cutting line. Cut the...

Abstract

The invention discloses a donkey hide treatment method before donkey-hide gelatin decoction and a process flow, and belongs to the field of donkey hide treatment. Donkey hide non-salt treatment is adopted for reducing generation of dust and industrial waste water in the donkey hide machining process, in the treatment process, the acid discharge process after the donkey hide is stripped from a living body is added, retaining of bad blood in a blood vessel in the donkey hide after slaughter can be reduced, foam extraction is facilitated in donkey-hide gelatin decoction, after the donkey hide iscleaned, the donkey hide is saved, contact with the nature pollution sources can be reduced, meanwhile, the pollution, caused by donkey hide outdoor airing, to the atmospheric environment is reduced,the cold storage technology is adopted in final storage, freshness of donkey hide is ensured, the donkey hide is kept in the fresh donkey hide state all the time, and the fresh collagen source is ensured.

Description

technical field [0001] The invention relates to the field of donkey hide treatment, in particular to a method and process flow for treating donkey hide before boiling donkey-hide gelatin. Background technique [0002] Donkey skin is the main raw material of donkey-hide gelatin. In the production process, when the backlog is too large and cannot be put into production in a short period of time, the storage method should be considered. Under normal circumstances, most factories adopt the salt-dried storage method, but because the pickling method is not The quality is not uniform, and even some small slaughterhouses use industrial salt. The slaughtered donkey skin cannot provide the quarantine certificate of the formal slaughterhouse, and after salting, soaking and washing will cause large industrial pollution wastewater, causing great pollution and waste, and the drying process will cause air pollution. This method of storage is very easy Cause the loss of protein or the dete...
