Description

Prepare seal-packed homemade-style method of ice cream and device

Technical field

The present invention relates to seal-packed so-called homemade-style method of ice cream of a kind of preparation and device.

Background technology

As well known by the skilled person in the art, the homemade-style ice cream mainly uses two kinds of systems to prepare.

First kind of system comprises following three steps: 1) stock blend is carried out pasteurization, by mixture is heated to approximately+85 ℃, and be quickly cooled to approximately+4 ℃, to eliminate flora; 2) to mixture behind the pasteurization in one suitable period of 4 ℃ of slakings, as 12 hours; 3) beat the mixture of slaking, and be cooled to the temperature that changes usually according to situation between-8 ℃ and-11 ℃, have solid structure up to ice-cream product, it is extracted out by whipper.

This system is exactly " classics " well known in the art or " tradition " method.

Therefore, by the long relatively time of the homemade-style ice cream needs of the produced in conventional processes that comprises above-mentioned three steps, it needs breadboard special management, especially in the summer that has the call, also needs the machine of three platform independent simultaneously: Pasteurizer, maturation tub and whipper.

Pasteurizer also can use as maturation tub, although in this case, before the bucket that comprises the slaking mixture is being cleared, can not be used for carrying out other pasteurization.

Second kind of system, " Trittico " well known in the art method (registration mark of Bravo S.p.A.) does not provide the mixture maturation stage: in other words, be heated to+85 ℃ mixture is by cooling immediately and beat simultaneously.

Therefore, " Trittico " proposed another kind of production method of ice cream---thoroughly having changed conventional method---by using single laboratory machine (single laboratory machine), wherein do not carry out the maturation stage of mixture: in other words, be heated to+85 ℃ mixture is by cooling immediately and beat simultaneously.

Like this, this device comprises the Pasteurizer and the whipper of an overlap joint, and it has conventional capacity and is connected to each other by the controlled conduit from the manual drives valve.

Pasteurizer and whipper can be worked in mode fully independently, therefore, use such machine, might the time some the mixture pasteurization, and beat the pasteurized mixture of previous quantity simultaneously.

Because the capacity of Pasteurizer and whipper is identical substantially, the time of pasteurization and whipping is also identical substantially, so, the ice cream of beating can be extracted out by whipper, pasteurized mixture (14) is discharged under the gravity effect in the empty whipper and is beaten, thereby vacates Pasteurizer, the new mixture of wanting pasteurization can be poured into wherein by (after the shut off valve), this machine is returned to original state, and wherein Pasteurizer and whipper are worked independently of one another simultaneously.

Just produced continuous production in this manner, wherein, per approximately 10～15 minutes (times of pasteurization and whipping in " Trittico " machine) just may extract the ice cream of aequum out, then it were placed on immediately to sell in the store display cabinet or preserve in cabinet.

The example of " Trittico " method and apparatus of Bravo S.p.A. is at patent IT-996, has in 102, IT-1,055,984 and EP-A-423,898 and describes and explanation, and these instructions will be understood that it is the application's a part.

Laboratory test is verified not to have architectural difference between by classics or conventional method and the ice cream by the production of " Trittico " method.

Because the appearance of " Trittico " device, the dark base of a fruit of malignant boil solid strong technology prejudice in root Shen malignant boil Shen has been overcome for many years, these prejudice are characterised in that, in order to produce certain mass homemade-style ice cream, need allow pasteurized mixture carry out slaking before beating fully.From this point, be necessary to use batch manufacturing method, it needs three kinds of machines: Pasteurizer, maturation tub and whipper.Have following defective: space, length, on the production time and especially mixture has serious contaminated risk (outside) transport process that is sent to another equipment from an equipment.

A significant advantage of " Trittico " is to have overcome this strong prejudice, by overlap joint and be connected to each other Pasteurizer and whipper has been formed the simple machine with continuous function, there, all pasteurized mixture is cleared in the following whipper, with work immediately (maturation stage in the middle of having reduced like this), another mixture in batches pasteurization is simultaneously poured into wherein immediately to empty back its at whipper, or the like.All these is not leave under the machine situation in a moment at mixture to take place, and therefore, is the environment of absolute health.

Generally speaking, the principal advantages of " Trittico " system especially from the health angle, may be summarized to be following:

-production process is closed circuit carries out, and wherein pasteurization can be carried out down at 95 ℃, under this temperature, cools off continuously immediately in sealing and shielded device, still is pumped by external pipe or connection for mixtures of liquids.

-same exist to some raw material any can not but possible really pollution, heat treatment guarantees that mixture is complete health.

-under refrigerated storage temperature all the other steps lack not total minimizing of freezing resting period of Buddhist monk, from the microbiology aspect, provide additional an assurance.

-planning to carry out the composition of pasteurization to keg, collecting the manual intervention of having avoided the operator in the final ice cream process fully from loading.

-aerobic-type may reduce by pollutant in a large number, because this production is to carry out in airtight fully device, does not have such preparation process: promptly under the situation that seal protection is not provided, mixture is deposited in the bucket; So just avoided may pollute from people or environment.

-should " Trittico " system realize mixing, pasteurization and freezing ideal process, wherein temperature reduced in the quite short time, walked around the dangerous temperature zone that comprises between 30 ℃ to 5 ℃ rapidly.

-this machine purging system takes place in closed circuit at one simultaneously, wherein adds entry and heats water to 95 ℃, is sent to whipper from heating region subsequently, and these do not need operator's manual intervention just can take place.

" Trittico " system of employing, can obtain to have the ice cream of optimum structure, because it is extremely cold by heat apace, and help the formation of small nut (reduced-nucleus) ice crystal, this has improved the stability of product in whole period, make it be not easy to be subjected to thermal shock, therefore, reduced the change on the sense organ.

According to the present invention, think above-mentioned special and proprietary feature with the Trittico method, and the good hygiene performance of the system that is particularly related to, be used for preparing the homemade-style ice cream that is packaged in airtight container, the cone shaped cup of described container such as different size, cup and/or keg, the capacity of container for example are that 50 grams are to 1 kilogram.

Ice-cream this packing is to use expensive industry and/or half-way unit to produce at present, and perhaps other manually extracts this homemade-style ice cream with spoon out from storage (shop showcase, refrigerator cabinet or other), fills and airtight container.

Yet this manual system of operating and being exposed in the environment on every side by the operator has brought serious risk of pollution to ice cream.
