MEAT GRINDERS 101

What is a meat grinder?

A meat grinder is a kitchen appliance used to finely chop or mince meat. It can either be a manual or an electric device. The meat is fed into a funnel on top of the grinder and then passes through a screw conveyor where it is minced by a cutting blade and a series of holes on a plate. This process produces ground meat, which can be used for various dishes like burgers, meatballs, sausages, and more.

Parts of a meat grinder

Hopper (or Feed Tube): This is where you insert chunks of meat to be ground. The hopper guides the meat into the feed tube, directing it towards the screw.

Screw (or Auger): This long, twisting blade pushes the meat through the grinder, moving it from the feed tube towards the blades and the grinding plate.

Blades: Sharp blades located at the end of the screw cut the meat into smaller pieces for grinding.

Grinding Plates (or Die): Round plates with multiple holes that determine the fineness or coarseness of the ground meat.

Cover: Usually placed over the blades and grinding plate for safe and efficient grinding.

Motor (in electric grinders): Powers the screw to enable the grinding process.

Hand Crank (in manual grinders): Used to manually turn the screw, moving meat through the blades and grinding plate.

Stabilizing Feet or Base: Keeps the grinder steady during use, especially important for manual grinders that require physical effort.

Pusher: Included to safely push meat into the grinder without risking injury to hands.

Sausage Attachment (optional): Allows ground meat to be directly funneled into sausage casings.

Electric vs. Manual Meat Grinders

Comparing electric and manual meat grinders reveals several key differences:

Manual	Electric
Requires physical effort, as you need to turn a hand crank.	Operates with an electric motor, requiring minimal effort.
Slower and best suited for smaller batches, speed depends on your effort.	Much faster and more efficient, especially for large quantities.
Requires more labor, can be tiring for large quantities.	Easier to use, beneficial for those who find manual grinding challenging.
Smaller, more portable, ideal for places without electricity.	Generally larger, less portable, needs an electrical outlet.
Less expensive and more budget-friendly.	More expensive due to the motor and additional features.
Allows for more hands-on control for desired textures.	Offers less tactile control over the grinding process.
Easier to maintain with fewer complex parts.	Requires careful maintenance, especially for motor and electrical components.
Quieter, involving only physical cranking.	Noisier due to the motor.
Suitable for smaller volumes of meat.	Better for grinding large amounts quickly.

Your choice between electric and manual meat grinders will depend on your specific needs, preferences, volume of meat to grind, budget, and physical ability. Electric grinders are great for frequent and large-volume grinding, while manual grinders are more suited for occasional, smaller tasks where control and portability are important.

How to use a meat grinder

Preparation: Cut the meat into pieces that fit the grinder’s hopper.

Feeding the Meat: Place the meat pieces into the hopper.

Grinding Process: The meat is pushed by the screw (or auger) towards the blades and grinding plate.

Cutting and Grinding: The blades cut the meat into smaller pieces, which are then forced through the holes in the grinding plate, determining the texture of the ground meat.

Output: The ground meat exits the grinder. If a sausage attachment is used, it can be directed into sausage casings.

Continuous Operation: The process continues as long as meat is fed into the grinder and it is in operation, either by hand cranking or powered by an electric motor.

Grinder Sizes

#5 or #8 Grinders: Smaller grinders, suitable for home use, ideal for grinding smaller quantities. The number corresponds to the diameter of the grinding plate in millimeters.

#12 or #22 Grinders: Medium-sized grinders, used in both home kitchens with higher meat grinding needs and in smaller commercial settings.

#32 or Larger Grinders: Large grinders designed for heavy-duty commercial use. Ideal for restaurants, butcher shops, or any place requiring large quantities of ground meat.

Each size has its specific use case, with smaller grinders being more suited for occasional, personal use, and larger ones for frequent or commercial use.

Grinding Plates and Knives

Grinding Plates (or Die):

Function: Grinding plates determine the texture of the ground meat. They have holes through which the meat is extruded after being cut by the knives.

Design: Typically round, flat discs made of durable metal. The size of the holes in the plate can vary.

Variety: Plates come with different hole sizes for varying textures. Smaller holes result in finely ground meat, suitable for sausages or hamburger patties, while larger holes yield a coarser grind, often used for chunkier applications like chili.

Knives (or Blades):

Function: Knives cut the meat into smaller pieces before it’s pushed through the grinding plate.

Design: Often have a cross-shape or star shape and are placed against the grinding plate.

Sharpness: Knives must be sharp to ensure efficient cutting. Dull knives can lead to poor grinding, smeared meat, and increased strain on the grinder.

Plate Differences

The primary difference between various meat grinder plates lies in the size of the holes, directly affecting the texture of the ground meat. Key distinctions:

Small Holes: Plates with small holes (around 1/8 inch or 3 mm) produce finely ground meat, often used for making bologna, hot dogs, or hamburger patties.

Medium Holes: Medium-sized holes (about 1/4 inch or 6 mm) are versatile and commonly used. Suitable for most ground meat applications, including sausages and ground beef for tacos or pasta dishes.

Large Holes: Plates with large holes (1/2 inch or 12 mm and up) yield a coarser grind. Ideal for more rustic sausages, chili, or recipes where a chunkier consistency is desired.

Specific Uses: Each plate size is designed for specific types of meat and end products. A finer grind might be preferred for certain sausages, while a coarser grind is better for dishes where the meat’s texture should be more pronounced.

Number of Holes: More holes generally allow for faster grinding.

Understanding the differences between plates allows for better selection based on the desired outcome of the ground meat. Meat grinders often come with a few different plates to accommodate various cooking needs.

Knife Differences

Differences between various knives (or blades) in meat grinders relate to design, compatibility, sharpness, and material:

Design and Shape: Most grinder knives have a standard cross-shaped or star-shaped design, ensuring effective meat cutting.

Compatibility: Knives must match the grinder size. A #12 grinder needs a #12 knife for efficient grinding.

Sharpness: Sharp knives cut meat cleanly, resulting in better texture and easier grinding. Over time, knives may need sharpening or replacement.

Material: Typically made of stainless steel or carbon steel. Stainless steel is resistant to rust, while carbon steel retains a sharper edge longer but may rust.

Frequency of Use: In commercial settings with intensive use, more durable, higher-grade knives might be preferred.
