With reference to instantiation, and further describe this utility model with reference to data it should be understood that these examples are simply
Explanation this utility model, rather than limit scope of the present utility model by any way.
The pre- cold loss of pig carcass in precooling process, SC sum, surface chromatic aberration is the testing index of this experiment.
Example 1
Material: 1440 pig carcass, each pig carcass nearly weighs 40kg.
Method: adjust the hydraulic pressure air pressure of spray and its numerical value of flow is: spray hydraulic pressure is 0.35mpa, air pressure is
0.2mpa, flow is 13l/h.
The program of setting intelligent control system, selects trunk to put track and (selects spray rail according to practical condition
Road), spray time, the spray frequency sample of each time period carries out pre- spray 30min, moistening and lowering temperature before entering storehouse.Hog on hook enters
Carry out intermittent shower behind storehouse, atomizing spray process is carried out using drip-proof shower nozzle to it, with reference to the spray of arrange parameter before.
Different disposal group is divided into tested for continuous 6 days, and every batch processing group puts into 240 pig carcass, puts into same pre-
In freezer.Pre- temperature of ice house is about -1 DEG C -7 DEG C, and air velocity is about 1m/s.
Test is divided into 6 different treatment groups (n=6), and the 1st group is blank group, and other 5 groups of spray times are respectively
8h, 9h, 10h, 11h, 12h (are shown in Table 1).The pre-coo time of 6 groups of trunks unified for 24h.The wet of pre- freezer will be controlled after 12h
, more than 90%, spray will be uniformly for degree.
Table 1 trunk spray-chilling condition
Testing index: the pre- cold loss of hog on hook, trunk surface chromatic aberration (l*, a*, b*), trunk SC sum.
Pre-cooling loss determination result:
As shown in Fig. 2 under the conditions of 24h routine pre-cooling, the pre- cold loss of hog on hook is 1.82g/100g, and using atomization
After spray, after spray 12h, the pre- cold loss of hog on hook is down to 0.62g/100g.Therefore, compared with conventional Pre-cooling Mode, atomizing spray
Pre- cold loss can be significantly reduced, bring certain economic benefit to enterprise.
Trunk surface yellowish pink measurement result:
Using portable colour difference meter, choose pig carcass back and sprayed position for a long time as sampled point, from each process
Group randomly selects 9 hogs on hook and measures its l*, a*, b*.
By Fig. 3,4,5 can be seen that the prolongation with the atomizing spray time, and trunk surface l* can dramatically increase, and a* can show
Write and reduce, reaction is exactly that spray time occurs, more than its surface of 10h, the phenomenon turned white in macroscopical organoleptic features, has a strong impact on sense
Official's character, therefore for the sensory properties of surface, 10h is optimal for spray.
Trunk surface microorganism measurement result:
This experiment is mainly the mensure impact to pork carcass surface total plate count for the atomizing spray.
Each treatment group is chosen and is randomly selected 9 hogs on hook, using wipe method in pork carcass surface back position 25cm2Take
Sample, takes routine techniquess to cultivate, and assay method reference food sanitary microorganism inspection total plate count and coliform measure
Program (gb 4789.2-2010).
The atomizing spray time has a significant impact for the total plate count on trunk surface as seen from Figure 6, during with spray
Between prolongation, its SC sum dramatically increases.But its trunk SC sum reaches after spray 12h
2.5logcfu.cm-2, less than standard value 3-4logcfu.cm-2
Therefore, spray time extends on the sum impact of trunk SC significantly, but result meets industry standard.
Example 2
Material: 19200 pig carcass, each pig carcass weighs about 40kg.
Method:
1. in four seasons (January, March, July, November), respectively choose 4800 pig carcass, be classified as three process
Group (atomizing spray, does not spray, enterprise's tradition spray).
2. treatment group 1 carries out pre- spray 30min, moistening and lowering temperature before entering storehouse.Hog on hook is carried out intermittently to hog on hook after entering storehouse
Spray, carries out atomizing spray process using drip-proof shower nozzle to it, and spray-water is 0 DEG C -5 DEG C, and front 4h sprays every 5min
30s, spray 6h below is to spray 30s every 30min.Spray hydraulic pressure is 0.35mpa, and air pressure is 0.2mpa, and flow is 13l/
h；. after treatment group 2 enters pre- freezer, trunk is not done with any spray process；Treatment group 3 takes enterprise current after entering pre- freezer
The manually spray being adopted, spray time is by manually controlling.
3. three treatment groups of each season are tested for continuous 4 days, and every batch processing group puts into 400 pig carcass, puts into
In same pre- freezer.Pre- temperature of ice house is about -1 DEG C～7 DEG C, and air velocity is about 1m/s.
Pre-cooling loss determination result:
As shown in fig. 7, in four seasons, the currently used spraying technique of enterprise, its pre- cold loss is respectively
1.50g/100g, 1.76g/100g, 1.47g/100g, 1.39g/100g.And pig can be significantly reduced using after novel atomized spray
Trunk pre-cooling is lost to 0.93g/100g, 1.18g/100g, 1.11g/100g, 0.84g/100g (p < 0.05).Therefore, using new
Atomizing spray method after, certain economic benefit can be brought to enterprise.
Trunk SC sum measurement result:
This experiment is mainly mensure impact to pork carcass surface total plate count in Various Seasonal atomizing spray.
Each treatment group is chosen and is randomly selected 9 hogs on hook, using wipe method in pork carcass surface back position 25cm2Take
Sample, takes routine techniquess to cultivate, and assay method reference food sanitary microorganism inspection total plate count and coliform measure
Program (gb 4789.2-2010).
As seen from Figure 8, in Various Seasonal, compared to the currently used spraying technique of enterprise, using atomization spray
Drench and the total plate count on trunk surface had a significant impact (p < 0.05), but due to enterprise butcher and administration of health in terms of
Reinforcement, even if adopting atomizing spray, its total family of trunk SC still be far smaller than industry standard 3～4logcfu.cm-2.Cause
This, notable on the sum impact of trunk SC using atomizing spray, but result meets industry standard.
Specific embodiment described herein is only that this utility model spirit is illustrated.This utility model institute
Belong to those skilled in the art described specific embodiment can be made with various modifications or supplement or using similar
Mode substitute, but without departing from of the present utility model spirit or surmount scope defined in appended claims.
