Types of Cookies in Automatic Cookie Production Line and Main Machinery of Biscuit Production Line

fully automatic cookie production line consists of a cookie molding machine, a tunnel-type hot-air circulation electric oven, a spray oiling machine, a turning machine, a cooling line, a cookie sorting machine, a cookie filling machine, and a packaging station. The entire line is controlled by CPU modules and features a back-mounted motor drive system. It boasts a compact structure and a high degree of automation, with all processes—from feeding, three-stage dough rolling, shaping, sugar sifting, conveying, waste removal, and recycling to baking, oil spraying, and cooling—completed automatically through mechatronic integration.

Classification and Characteristics of Cookies

The primary ingredient in cookies is wheat flour, supplemented with sugars, fats, eggs, dairy products, and other auxiliary ingredients. Depending on the recipe and production process, sweet cookies can be broadly categorized into two types: chewy cookies and shortbread cookies. Chewy cookies are typically molded with concave patterns and feature pinholes on the surface. The surface of the finished product is flat and smooth, with a layered cross-section. When chewed, they offer a crisp texture and are chewy, with crispness being their distinctive feature. The ratio of sugar and fat in chewy cookies is lower than in shortbread cookies. Typically, sugar accounts for less than 30% of the total weight, and fat accounts for less than 20%. Shortbread cookies are characterized by raised patterns on the surface, distinct designs, and a fine, dense texture, with fat content ranging from 14% to 30% of the flour weight. For some special sweet, crumbly varieties, the fat content can reach as high as 50%.
· Shortbread Cookies: A baked good made primarily from wheat flour, sugar, and fat, with the addition of leavening agents and other ingredients. Produced through a cold-dough process involving mixing, rolling, die-cutting, or stamping, followed by baking. These cookies typically feature raised patterns, a porous cross-sectional structure, and a light, crumbly texture. Examples include butter cookies, scallion cookies, sesame cookies, and egg shortbread cookies.
· Chewy Cookies: Made primarily from wheat flour, sugar, and fats, with the addition of leavening agents, improvers, and other ingredients. Produced through a hot-mixing process involving dough mixing, rolling, die-cutting, or stamping, followed by baking. These cookies typically feature concave patterns, a smooth and flat surface with pinholes, a layered cross-section, and a crisp texture. Examples include milk cookies, vanilla cookies, and egg-flavored cookies.
· Leavened cookies: Baked goods made primarily from wheat flour, sugar, and fats, using yeast as a leavening agent, with various other ingredients added. They are produced through fermentation, dough mixing, rolling, layering, and baking, resulting in a crisp texture and the distinctive aroma characteristic of leavened products. Leavened cookies are also known as chocolate frames and are classified into savory and sweet varieties based on their recipes.
· Thin, crispy cookies: Thin, crispy baked goods made primarily from wheat flour, sugar, and fat, with added seasonings and other ingredients, and produced through mixing, shaping, and baking.
· Sandwich cookies: Baked goods consisting of two cookies with a filling—such as sugar, fat, or jam—sandwiched between them.
· Egg-based cookies: Crispy baked goods made primarily from wheat flour, sugar, and eggs, with the addition of leavening agents and flavorings, produced through beating, battering, pouring, and baking; commonly known as egg-based cookies.
· Egg Rolls: Crispy baked goods made primarily from wheat flour, sugar, and eggs, with the addition of leavening agents, flavorings, and other ingredients, produced through beating, battering (with or without fermentation), pouring or coating, and baking and rolling.
· Decorated cookies: A crumbly baked good made primarily from wheat flour, sugar, and fat, with the addition of dairy products, egg products, leavening agents, and flavorings. It is produced through kneading, shaping, baking, cooling, decorating the surface with sugar flowers, and drying.
· Boiled cookies: A light, crumbly baked good made primarily from wheat flour, sugar, and eggs, with added leavening agents. The process involves mixing the dough, multiple rolling steps, shaping, blanching in boiling water, soaking in cold water, and baking, resulting in a product with a rich aroma.
