Detailed Description

In order to make the description of the present invention more complete and complete, reference is made to the accompanying drawings and the following description of various embodiments, in which like reference numerals refer to the same or similar elements. In other instances, well-known elements and steps have not been described in detail in order to avoid unnecessarily obscuring the present invention.

In the description and claims, the articles "a" and "an" may refer broadly to the singular or the plural, unless the context specifically states otherwise.

Referring to fig. 1 and 2, fig. 1 illustrates steps of a method for fixing solid particles to a dry sheet according to an embodiment of the present invention, and fig. 2 illustrates a schematic diagram of an apparatus according to an embodiment of the present invention.

The method 10 of the present invention for immobilizing solid particles on a dry sheet is performed by an apparatus 100. The apparatus 100 comprises two cylinders (102,104), a watering device 105, and a doctor blade 110. A syringe 105 is used to inject a mixed slurry of solid particles 108 and food slurry 106 onto the two rollers (102, 104). The doctor blade 110 is used to scrape the sheet (dried food slurry 106) with the solid particles 108 fixed to it off the surface of the two cylinders (102, 104). The apparatus 100 depicted in fig. 2 is merely exemplary, and the two rollers may not be of the same size (e.g., a large roller with a small roller); the two rollers are not limited to be horizontally arranged side by side (for example, the small roller can be positioned above the large roller); the rolling direction of the two rollers is not limited to the direction in the drawing (for example, the two rollers roll in the opposite directions of the direction in the drawing).

The solid particles may include nut seed particles (e.g., almond, cashew, walnut, pine nut, pistachio nut, macadamia nut, sunflower seed, pumpkin seed, melon seed, black sesame, white sesame, peanut), cereal grain particles (e.g., brown rice, purple rice, white rice, wheat, barley, oat, buckwheat, quinoa, corn, coix seed, millet, sweet potato, taro, pumpkin, yam, lotus root), bean particles (e.g., red bean, mung bean, black bean, flower bean, broad bean, emperor bean), and other granular foods (e.g., chestnut, lotus seed, chia seed), but not limited thereto.

In step 12, the spacing between the two rollers (102,104) is set to a predetermined range. The spacing between the two rollers is used to control the thickness of the dried sheet of food slurry 106, which is also related to the size of the food particles to be held. Thicker flakes are better able to hold food particles of matching size so that the food particles can be heated together in the drum without prematurely flaking off the drum surface. The spacing between the two rollers is preferably, but not limited to, greater than the size of the food particles, while being less likely to crush the food particles or better able to maintain the integrity of the food particles. In addition, the spacing between the two drums also affects the drying time required for the food slurry 106 to dry into a sheet on the drums.

In step 14, both rollers are rotated (e.g., along arrows in the figure) and the temperature of both rollers (102,104) is heated to a predetermined range. The two drums are used to provide sufficient heat to dry and sterilize the food slurry and food particles.

In steps 16, 18, a plurality of solid particles 108 are mixed with a food slurry 106 having a suitable viscosity range and poured onto two rollers (102,104) by a pouring head 105. At this point, the rotating rollers (102,104) pass the food slurry 106 with the food particles 108 immobilized thereon between the rollers (102,104) to control the thickness of the dried sheet of food.

In step 20, when the mixture of the food slurry 106 and the solid particles 108 adheres to the two rollers (102,104) for a suitable time, the sheet formed by drying the food slurry 106 and the solid particles 108 is scraped off the surfaces of the two rollers (102,104) by the scraper 110. In practice, the drying time from the contact of the slurry 106 on the surface of the drum to the position of the doctor blade 110 is controlled by controlling the rotational speed on the two drums (102, 104).

In order for the food slurry 106 to firmly adhere to the solid particles 108, the viscosity of the food slurry 106 needs to be matched to the spacing between the two rollers, the temperature of the rollers, and the drying time to produce a dried and sterilized dry tablet food. Examples satisfying this need are listed below.

In the first embodiment, the viscosity of the food slurry 106 is controlled to be in the range of 50,000cp to 70,000cp, and it is necessary to match the gap between two drums of 11 mm to 25 mm, the drum heating temperature of 125 ℃ to 155 ℃ and the drying time of 350 seconds to 530 seconds.

The formulation of this example food slurry 106 may comprise wheat flour 51 wt%, granulated sugar 6 wt% and water 39 wt% to obtain a food slurry of viscosity 63,400cp, with 4 wt% chia seed solid particles added. The user can slightly adjust the water content to obtain a viscosity range of 50,000cp to 70,000cp, i.e. the distance between the two rollers, the heating temperature of the rollers and the drying time of the rollers can be matched with the above proper range.

When the method 10 is carried out outside the above-mentioned appropriate range, it is possible to produce an unacceptable dry tablet food. For example, when the drum pitch is less than 11 mm, the drum heating temperature is higher than 155 ℃ and the drying time exceeds 530 seconds, a scorched dry sheet food is easily produced. When the distance between the rollers is more than 25 mm, the heating temperature of the rollers is lower than 125 ℃, and the drying time is less than 350 seconds, the sheet food which is not completely dried, incompletely sterilized and has a shortened shelf life is easily produced.

In the second embodiment, the viscosity of the food slurry 106 is controlled to be in the range of 30,000cp to 52,000cp, and it is necessary to match the gap between two drums of 10 mm to 20 mm, the drum heating temperature of 130 ℃ to 160 ℃ and the drying time of 200 seconds to 480 seconds.

The formulation of this example slurry 106 may comprise 23 wt% barley flour, 4 wt% oat flour, 12 wt% granulated sugar and 55 wt% water to obtain a slurry having a viscosity of 50,000cp, with 6 wt% sesame solids added. The user can slightly adjust the water content to obtain a viscosity range of 30,000cp to 52,000cp, i.e. the distance between the two rollers, the heating temperature of the rollers and the drying time of the rollers can be matched with the appropriate range.

When the method 10 is carried out outside the above-mentioned appropriate range, it is possible to produce an unacceptable dry tablet food. For example, when the drum pitch is less than 10 mm, the drum heating temperature is higher than 160 ℃ and the drying time exceeds 480 seconds, a scorched dry sheet food is easily produced. When the distance between the rollers is more than 20 mm, the heating temperature of the rollers is lower than 130 ℃ and the drying time is less than 200 seconds, the sheet food which is not completely dried, incompletely sterilized and has a shortened shelf life is easily produced.

In the third embodiment, the viscosity of the food slurry 106 is controlled to be in the range of 25,000cp to 32,000cp, and it is necessary to match the gap between two drums of 6 mm to 12 mm, the drum heating temperature of 145 ℃ to 180 ℃ and the drying time of 100 seconds to 250 seconds.

The formulation of this example food slurry 106 may comprise 36 wt% flour, 5 wt% oat flour, 9 wt% granulated sugar and 47 wt% water to obtain a food slurry with a viscosity of 27,000cp, with the addition of 3 wt% sesame solids. The user can slightly adjust the water content to obtain a viscosity range of 25,000cp to 32,000cp, i.e. the distance between the two rollers, the heating temperature of the rollers and the drying time of the rollers can be matched with the above proper range.

When the method 10 is carried out outside the above-mentioned appropriate range, it is possible to produce an unacceptable dry tablet food. For example, when the drum pitch is less than 6 mm, the drum heating temperature is higher than 180 ℃ and the drying time exceeds 250 seconds, a scorched dry plate-like food is easily produced. When the interval between the rollers is more than 12 mm, the heating temperature of the rollers is lower than 145 ℃ and the drying time is less than 100 seconds, the sheet food which is not completely dried, incompletely sterilized and has a shortened shelf life is easily produced.

In the fourth embodiment, the viscosity of the food slurry 106 is controlled to be in the range of 65,000cp to 100,000cp, and it is necessary to match the gap between two drums of 20 mm to 30 mm, the drum heating temperature of 120 ℃ to 150 ℃ and the drying time of 400 seconds to 600 seconds.

The formulation of the food slurry 106 of this example may comprise 37 wt% wheat flour, 11 wt% oat flour, 4 wt% rice flour, 6 wt% granulated sugar and 37 wt% water to obtain a food slurry with a viscosity of 90,000cp, with 5 wt% sesame solid particles added. The user can slightly adjust the water content to obtain a viscosity range of 65,000cp to 100,000cp, i.e. the distance between the two rollers, the heating temperature of the rollers and the drying time of the rollers can be matched with the above proper range.

When the method 10 is carried out outside the above-mentioned appropriate range, it is possible to produce an unacceptable dry tablet food. For example, when the drum pitch is less than 20 mm, the drum heating temperature is higher than 150 ℃ and the drying time exceeds 600 seconds, a scorched dry sheet food is easily produced. When the distance between the rollers is more than 30 mm, the heating temperature of the rollers is lower than 120 ℃ and the drying time is less than 400 seconds, the sheet food which is not completely dried, incompletely sterilized and has a shortened shelf life is easily produced.

The manufacturing method of the dry sheet-shaped object provides a proper process range so as to manufacture the sheet-shaped object containing complete solid particles, and the dry sheet-shaped object and the solid particles thereof can be properly dried and sterilized and are easy to store, thereby providing richer nutrition and better food safety for eaters.

Although the present invention has been described with reference to the above embodiments, it should be understood that various changes and modifications can be made therein by those skilled in the art without departing from the spirit and scope of the invention.
