Letter biscuits are biscuits with letter shapes as their distinctive features, and usually have the following characteristics:
Appearance Characteristics of Letter Biscuits
Shape: Its most prominent feature is that it is made into the shape of letters. Each letter has a relatively independent and complete shape. The edges of the biscuits are usually regular and clear, allowing consumers to easily identify which letter it is.
Size: Generally speaking, the size of letter biscuits is not too large. Usually, the length of a single letter is about 2-5 cm and the thickness is between 0.3-0.8 cm. This size is convenient for consumers to eat and is also convenient for processing and baking during the production process.
Taste Characteristics of Letter Biscuits
Diverse taste: Depending on the production process and raw materials, the taste of letter biscuits is also different. Some letter biscuits have a crispy taste and will break into small pieces with a light bite, such as soda letter biscuits; some have a relatively hard taste and need to be chewed slowly, such as some whole wheat letter biscuits; and some letter biscuits with a lot of fat and sugar added have a soft, sweet taste.
Rich flavors: The flavors are very rich. The common ones are original flavors, which mainly reflect the fragrance of raw materials such as flour and butter; there are also chocolate, strawberry, milk and other fruit and milk flavors. These flavors are mainly achieved by adding corresponding flavors, fruit powder or chocolate sauce and other raw materials, which meet the taste needs of different consumers.
Letter Biscuit Production in Biscuit Line
Raw material preparation: Use high-gluten flour or low-gluten flour to provide the structure and texture of the biscuits. Prepare different ingredients and adjust the flavors as needed.
Mixing: Pour the weighed flour into the mixer, then add other wet ingredients such as sugar, eggs, milk, etc., and continue mixing until a smooth and elastic dough is formed.
Roller stamping: According to the style and size of the required letters, select the appropriate roller stamping mold and install it on the biscuit forming machine. The roller stamping mold is engraved with pits in the shape of various letters to ensure that the mold surface is smooth and undamaged to ensure the quality of biscuit molding.
Baking: Preheat the oven to an appropriate temperature, usually around 180-200°C. Place the baking sheet with the letter cookies in the preheated oven and bake for how long depending on the size and thickness of the cookies.
Cooling and packaging: After the baked letter biscuits are out of the oven, the biscuits cool naturally. The cooled letter biscuits are transported to the packaging machine through a conveyor belt. The packaging machine puts a certain number of biscuits into packaging bags or boxes according to the set packaging specifications.
Letter Biscuit Line Selection
In addition to considering some general factors of ordinary biscuit production lines, the selection of letter biscuit production lines also has its own special considerations.
Mold accuracy: The shape of letter biscuits requires precision, so the mold accuracy of the production line is crucial. High-quality molds can ensure that the edges of the letters are clear and complete, without deformation or blur. For example, the details of the letters on the biscuits, such as the thickness of the lines and the curvature of the corners, can be accurately presented.
Temperature uniformity of baking equipment: Letter biscuits have relatively small and irregular shapes, so they require higher uniformity of baking temperature.
Baking time control accuracy: Letter biscuits of different sizes and thicknesses require precise control of baking time to achieve the best taste and color. The baking equipment of the production line should have precise time control function, and the time adjustment accuracy can reach minutes or even seconds to ensure that each batch of letter biscuits can be baked just right.
