Background technology
On current frozen market, it is more and more that upper and lower two biscuits press from both sides ice-cream sandwich product, but existing sandwich product is because its architectural feature is limit, biscuit sheet directly contacts with ice cream material, in the storage and transportation in later stage, the easy moisture absorption and deformation of biscuit, causes the biscuit mouthfeel of the sandwich product that consumer buys not crisp, outward appearance irregularity.And at process aspect, on market, the most of slice that adopts of the enterprise of existing production ice cream sandwich is produced, secondary bonding biscuit after excision forming, this technology utilization tunnel is generally to carry out according to following steps: put a slice biscuit → ice cream biscuit excision forming (falling on biscuit) → bonding another sheet biscuit → slotting chopsticks (or not inserting chopsticks) → quick-frozen → packing → moulding; Wherein, ice cream biscuit adopts excision forming, and the drop temperature of freezing machine is-6 to-4.5 ℃ of left and right, and the temperature of freeze tunnel is-46 ℃ of left and right.In this technique, freeze tunnel employing is air-cooled lowers the temperature to product, and temperature fall time is long, humidity is high, so greatly limited product yield, and caused the distortion of feeling like jelly of the easy moisture absorption of biscuit, thus this type of product yield low, go out into low, and producing cost is high, price is also high.
Summary of the invention
For solving the problems of the technologies described above, the object of the present invention is to provide a kind of self-service ice cream sandwich, by biscuit and ice cream semi-finished product are packed separately, the mode then combining before edible, obtains a kind of ice cream sandwich that can keep biscuit good taste.
The present invention also aims to provide the production method of above-mentioned ice cream sandwich, the method has the advantages that output is large, yield is high.
For achieving the above object, first the present invention provides a kind of self-service ice cream sandwich, and it comprises and be positioned over the ice cream semi-finished product of holder in box and be positioned over two biscuits in Biscuit Wrapping Bag, and wherein, described holder box and Biscuit Wrapping Bag are deposited separately.
Self-service ice cream sandwich provided by the present invention is that then two biscuits and ice cream semi-finished product are positioned in the outer packaging bag of this self-service ice cream sandwich with packing splendid attire separately respectively, two biscuits and ice cream semi-finished product are combined before edible by eater, obtained ice cream sandwich and eat.By separated, can guarantee that biscuit can moisture absorption and deformation, to keep its crisp mouthfeel and regular outward appearance.The shape of holder box can adapt with the half-finished shape of ice cream, to guarantee that product can not deform in storage and transportation.
" ice cream semi-finished product " of the present invention do not refer to not the ice cream combining with biscuit, except shape, itself and common ice cream be do not have differentiated.The half-finished raw material of ice cream involved in the present invention and proportioning all can be selected in conventional ice cream materials and proportioning, but its preparation method is different from conventional ice cream sandwich product.
In above-mentioned self-service ice cream sandwich, preferably, ice cream semi-finished product are a cuboid, and, on four long limits of this cuboid, be respectively provided with a fin, a groove of one side composition of two described fins and described cuboid, the shape of this groove and the shape of described biscuit match.The ice cream semi-finished product of this self-service ice cream sandwich provided by the present invention can have the shape of special processing, so that eater combines biscuit and ice cream semi-finished product, two biscuits can insert respectively in two grooves, and fin can be fixed biscuit, prevent slippage, thus, two biscuits and ice cream semi-finished product can form complete cuboid, i.e. an ice cream sandwich.On these ice cream semi-finished product, be inserted with ice cream chopsticks, to carry out in process of production the demoulding.
In above-mentioned self-service ice cream sandwich, preferably, the height of fin is identical with the thickness of described biscuit.
In above-mentioned self-service ice cream sandwich, preferably, the cross section of fin is rectangle.
In above-mentioned self-service ice cream sandwich, preferably, the width of fin is 4-6mm.If the width of fin is too little, can easily there is modification in ice cream, be difficult to reach the effect of fixing biscuit in the process of circulation in later stage; If the width of fin is too large, ice cream profile will be attractive in appearance not.
In above-mentioned self-service ice cream sandwich, preferably, groove is positioned on the face of described cuboid area maximum.
The present invention also provides the production method of above-mentioned self-service ice cream sandwich, and it adopts pattern production line to produce, and the method can comprise the following steps:
Make ice-cream feed liquid through congealing, fill with mould, slotting chopsticks, freeze, the demoulding, then utilize holder box to pack, obtain described ice cream semi-finished product, in the process of wherein congealing, the drop temperature of freezing machine is-3 to-1.5 ℃, the temperature of freezing is-40 to-45 ℃, and the temperature of the demoulding water adopting when the demoulding is 18-30 ℃;
By two Biscuit packages in Biscuit Wrapping Bag;
By being packaged in the ice cream semi-finished product of holder in box and being packaged in Biscuit package in Biscuit Wrapping Bag in ice cream outer packaging bag, obtain described self-service ice cream sandwich.
In aforementioned production method, biscuit can be purchased, as long as the groove shapes on its shape and ice cream semi-finished product adapts, its sanitary index etc. meets corresponding sanitary standard.
Self-service ice cream sandwich provided by the present invention is by biscuit and the independent packaging respectively of ice cream semi-finished product, and then pack in same packaging bag, the easy moisture absorption and deformation of biscuit, the mouthfeel that have solved existing ice cream sandwich product are bad, the problem of outward appearance irregularity, and, adopt this packaged form can adopt effect yarn to produce, can solve the problem that traditional ice cream sandwich can only utilize tunnel line to produce, greatly improve output and the yield of product.
The specific embodiment
Understand for technical characterictic of the present invention, object and beneficial effect being had more clearly, existing technical scheme of the present invention is carried out to following detailed description, but can not be interpreted as restriction that can practical range of the present invention.
Embodiment 1
The present embodiment provides a kind of self-service ice cream sandwich, and it comprises two biscuits, ice cream semi-finished product, holder box, a Biscuit Wrapping Bag and an ice cream outer packaging bag, wherein:
Two Biscuit packages are in Biscuit Wrapping Bag;
Ice cream semi finished package is in holder box, these ice cream semi-finished product are a cuboid (as shown in Figure 1), the face of its area maximum is provided with four fins, and two fins and an above-mentioned groove of face composition, and the shape of this groove and the shape of biscuit match; On ice cream semi-finished product, there are ice cream chopsticks;
Biscuit Wrapping Bag and holder box are packaged in ice cream outer packaging bag.
In the time that eater is edible, first two biscuits 1 and ice cream semi-finished product 2 are taken out respectively from Biscuit Wrapping Bag and holder box, then two biscuits 1 are inserted respectively in the groove of ice cream semi-finished product 2, fin just in time can be by fixing biscuit 1, thereby obtain a complete ice cream sandwich, its cross section as shown in Figure 2.
