So, whether you are grinding spices, herbs, grains, or other food ingredients, make sure to choose the right industrial grinder and maintain it properly to ensure efficient and safe food processing.
An industrial food grinder is not a piece of equipment used for short-batch processes that are manually intensive. You would not find one in the home kitchen, for example. These are large, industrial-grade pieces of machinery that deliver output and uniformity.
As a general rule, these grinders tend to exist in highly automated and controlled processes. They’re popular in settings where companies are trying to create uniform products in uniform batches. This makes them perfect for commercial food production, for example. They’re also a popular go-to in the world of continuous processing, where they stand to enhance productivity.
While not everyone needs an industrial grinder, most operations reach a point where their old batch-style machines can’t keep up, so they decide to introduce some more powerful equipment.
Dicers are commonly used to make prepared foods, such as veggies and toppings. Take prepared, pre-chopped chicken, for example – it goes through a commercial-grade dicer outfitted with circular blades. This system offers outstanding precision, high output, and less waste.
Dicers also produce visually appealing food products, which can help increase a company’s sales. By supporting faster, more sanitary food production, dicers have quickly become a favorite tool in the commercial food production industry.
Generally speaking. Most pieces of size reduction equipment require a metered feed. This is true for the following reasons:
While stainless steel motors seem obvious in the world of food production, for years they were relatively unavailable, especially with motors above 10 horsepower. While washdown-duty motors have been available (motors specifically designed for use in food processing and other applications where the equipment is routinely exposed to washdown, chemicals, humidity, and moisture,) they were all painted. Food processing standards have been increasing over the years. Today, the industry has very high standards for both food safety and cleanliness. The widespread demand for stainless steel motors grew from these sensibly high standards and process equipment manufacturers can now affordably offer these options.
Sometimes, food grinding can’t be a “one and done” process. When it comes to size reduction, the laws of physics dictate that you can only do so much work in a single pass.
A classic example is in the reduction of a twenty-pound wheel of parmesan cheese.
Say you need to grate this large wheel of cheese for pizza topping. Pizza topping requires a nice, fine grind with no chunks or large clumps of product. If you try to reduce the entire wheel in a single pass, though, you’ll end up with one of two outcomes: you’ll either overheat your material or destroy your machine.
Instead, begin by reducing the wheel of cheese into small pieces via an initial grinding pass – chunks of 0.75”, for example. Once you’ve made a single pass and reduced the material to 0.75”, you can take this output and grind it once again, through a different machine, to create a smaller particle size. This is called double pass grinding. While double pass grinding is common in commercial uses, it’s also utilized by at-home chefs grinding meats and other products.
The process of double pass grinding is essential for a few reasons. The first and most obvious is that it reduces the load on both machines during passes. The amount of load it takes to process a large product directly into its final form factor can be massive. For example, the rotating imbalance of flinging around a 20 pound block of material is enormous and potentially damaging. The objective for companies is to get the material through the mill as quickly as possible without negatively impacting the product or the machinery. Double pass grinding can greatly increase the efficiency of the size reduction operation. This consideration is especially critical for a product which will melt under high heat loads.
55-gallon drums are a convenient way to acquire frozen product, but can be a pain in the neck to deal with. Not only are these drums large and unwieldy to move around, but they take a long time to thaw. At most plants, food processing companies deal with this problem by leaving drums of material outdoors to thaw.
The big issues with that solution are that they don’t let them thaw out long enough and the center remains frozen. Alternatively, companies let them soften too long, risking spoilage. If you have a frozen kernel in the middle of the drum, the core will mostly be water.
Orange juice concentrate is a great example: the water freezes before the sugar, so you wind up with a frozen drum of juice that’s mostly sugar on the outside with a hard kernel of ice in the middle. To transform it back to orange juice, you then have to break up the ice ball, add water, and mix.
Introducing size reduction equipment not only dramatically speeds up the thawing process, but also prevents damage from under-thawed material in downstream processes.
The easiest way to deal with these large drums of material is to conduct the entire process while the material is still frozen. Unfortunately, there’s not much equipment out there that can do it. Most rotary chippers designed for this are ineffective and slow. Other pieces of equipment, like the Reitz Extractor, for example, serve different purposes. The Extractor is a large, stainless steel, high-capacity, meat grinder. While the machinery is robust, it is too expensive or unsanitary for many companies.
Because of that, some companies use Crushers, which is what we manufacture here at Corenco. Crushers are a less costly method of processing large amounts of frozen material, from 5-gallon buckets to 55-gallon drums. Thaw 55-gallon Drums of Frozen Product – These Crushers reduce content down to softball-sized or smaller chunks.
