Many friends have eaten this snack when they were young, especially rice and fruit with a sandwich, which tastes very good. So what's the filling in the sandwich rice fruit?
Generally speaking, the sandwich in the sandwich rice fruit takes cream as the carrier of the sandwich material, and various fillings, such as peanut butter, chocolate sauce, syrup, etc., which have been crushed and screened by 60 mesh are added in proportion. The hollow tube is produced by an expander, and then the core material is injected into the rice fruit by a sandwich machine.
Second, the technological process of making sandwich rice fruit machine
Sandwiched rice and fruit snacks in the market are generally industrialized, and the machinery and equipment used are dough mixer, feeder, bulking machine, sandwich machine, molding cutter, elevator, oven and so on. The specific production process is as follows:
1, selection and impurity removal
Remove foreign bodies such as sand and stones from rice and corn with a stone remover.
2, crushing and sieving
The rice and corn after impurity removal are respectively crushed and sieved by a 20-mesh sieve.
mix
Mix rice flour and corn flour evenly in proportion, and keep the moisture content of the mixed raw materials at 10%- 14%.
Step 4 make stuffing
Cream has good stability and lubricity, which can make the product have good flavor. Therefore, it is ideal to use cream as the carrier of sandwiches. Heat the pure cream to melt, then cool it to about 40℃, add all kinds of crushed fillings with 60 mesh sieve in proportion, and stir evenly. In order to ensure the product quality, the cream should be added in an appropriate amount to ensure the uniform dilution and good fluidity of the materials. Cream should be pure cream, not mixed with water.
5, grain expansion and filling
This is the key process of product production. The quality of material expansion directly affects the texture and taste of finished products. In the process of extrusion, the material changes into liquid gel state through high temperature and high pressure, and is extruded evenly and stably through a specially designed sandwich die. At the same time, the stuffing is extruded by a centripetal extruder, evenly injected into the puffed cake by a sandwich die, and extruded together with the puffed material. During extrusion, the moisture content of the material decreased to 9%- 10%.
6. Plastic surgery
After the filled puffed material is extruded from the die hole, it needs to be dragged to the molding machine, squeezed by two molding rollers, and then cut into puffed food with a certain length and uniform thickness by the cutter. At this time, the material cools and the water content drops to 6%-8%.
Step 7 bake
The purpose of baking is to improve the taste and shelf life of products. By baking, some fillings can be changed from raw to cooked, resulting in pleasant fragrance. After baking, the moisture content of the material is reduced to 2%-3%.
8. Spray oil for seasoning
The process is carried out in the barrel, and the purpose of oil injection is to prevent the product from absorbing moisture, give the product a certain stability and extend the shelf life; Spraying seasoning is to improve the taste and flavor. With the rotation of the drum, the material enters from one end and comes out from the other. Oil is sprayed when the material enters the drum, and the oil is evenly coated on the surface of the material by tumbling and stirring; When the material passes through the middle of the drum, the seasoning is added, and only the cloth is stirred, and the sandwich rice fruit product comes out of the drum.
9. Packaging
Products are sealed with polyethylene plastic film for pillow packaging machine, which requires sealing, beauty and neatness.
