curd mill

Types of curd mills

A curd mill, also known as a cheese cutter or cheese granulator, is used to cut cheese blocks or curd into smaller pieces for further processing. Curd milling refers to the process of cutting cheese into small granules or particles to facilitate melting, mixing, and production of cheese products like cheese sauce, shredded cheese, or cheese blends.

Generally, there are several variations of cheese mills designed to suit different kinds of uses and preferences. The first type is the manually operated cheese mill, which is often used at home and is not industrial in any way. This machine usually consists of a handle that is required to be rotated to cut the cheese into smaller pieces or curds. Its simplicity and ease of use allow users to have better control over the size of the cheese curd. On the other hand, automatic Curd mills come in different shapes and sizes, all designed to ensure that the process of cutting cheese is smooth and efficient. Some of them even come with special features that allow subtitles for better formatting.

Another example of a curd mill is the stainless steel Curd cutter, which is made of stainless steel material. This deviates from the traditional metal and plastic material combinations of cheese cutters. Stainless steel cheese curd mills have several advantages, the main one being that they are durable, corrosion resistant, and hygienic. These qualities make them long-lasting and provide quality service over a long period of time.

Industrial-scale cheese mills are used for large-scale production in industrial settings. These machines are typically motorized and feature heavy-duty blades or bands to cut large volumes of cheese quickly and efficiently. They may have adjustable settings to control the size of the cheese granules and can process different types of cheese. Specialized cheese mills are designed for specific types of cheese or applications. For example, soft cheese mills have gentle cutting mechanisms to prevent damaging soft cheese products. Hard cheese mills may have more robust blades to handle the density of hard cheese.

Specification and Maintenance

The following specifications are primarily associated with industrial-scale curd mills, which have much higher capacities than those used in domestic settings.

• Capacity: Curds can be processed in volumes of up to several thousand liters, and milk throughput can be from 1,500 to 8,000 liters per hour. Such enormous capacities require that curd mills have robust infrastructures and powerful motors. Their processing capabilities need to be fast and efficient so that large amounts of dairy products can be produced at a low cost and within a short period of time.
• Product Type: Different types of dairy products, such as cheese, tofu, and certain other fermented dairy products, require specific kinds of curd mills. Generally, there are two key types industrial-scale curd mills are designed to process distinct dairy products. Disc mills use grinding discs to crush curds. They are one of the most widely used curd mills, especially in the production of cheese, where precisely crushing the curds is essential for achieving the desired cheese texture and composition. Furthermore, disc mills are also adapted for processing other dairy products, like tofu and fermented dairy beverages. Hammer mills use high-speed hammers to smash curds. They are commonly used in the production of certain types of cheese and fermented dairy products. Some specific designs of hammer mills are also used to process tofu. Collide mills, which use grinding plates to crush curds, are mostly used in the production of cheese and fermented dairy products. Clamp mills work by applying a clamping force to hold the curds in place while grinding or crushing. They are not very popular among industrial-scale curd mills, but some specific designs use a combination of clamps and plates to process the curds.
• Material: The materials that are used to construct curd mills are strong, durable, non-corrosive, and hygienic. More importantly, they can withstand the milling process and fouling by residues of curd. This prevents the detrimental development of bacteria and other microorganisms. Stainless steel, an alloy composed mainly of iron and chromium, is resistant to rust and suitable for use in high-temperature and humid environments. It also meets food industry standards, alongside plastic and rubber products, to ensure that food safety is never compromised. Rubber is sturdy yet flexible, soft, and non-slippery. Plastic is lightweight, easy to clean, and resistant to chemical damage. Not only does it retain its quality for a long time, but it's also easy to mold into various shapes and sizes, which are ideal for food processing machinery.
• Energy Consumption: Energy consumption is a crucial factor for large-scale processing facilities. The capacity of curd mills is directly linked to energy consumption. For instance, hammer mills typically consume around 0.8-1.5 kWh per ton of processed curds at large-scale capacities. Disc mills1.5-3 kWh per ton. The energy requirements of curd milling machines should correspond with their processing capacities, ensuring effective resource utilization and reduced production expenses for processing facilities.

An industrial-scale curd mill's essential parts are its motor, rollers, housing, screen, and exit. A good maintenance routine ensures they always bond, pull, crush, and release fresh dairy produce. Rigorous cleaning is imperative. The screens should be clear of any residues to prevent bacterial growth. The hoppers, roller compartments, pulleys, and any other parts should be cleaned on a regular basis. Rinsed thoroughly, all pollutants should be disposed of, and the machine should be sanitized before use.
