Winnowing machine for cocoa and chocolate processing

The process of winnowing is an old school agricultural method used to separate the edible part of crops from the chaff. Farmers would use a winnowing basket or a simple hand-held winnowing tool to remove the lighter chaff from the heavier grain. As technology advanced, winnowing machines were developed to automate this process, allowing for greater efficiency and productivity in farming and harvesting. Today, winnowing machines are used in a variety of industries, including cocoa and chocolate processing equipment. Royal Duyvis Wiener BV is a global manufacturer of this kind of equipment with an impressive track record in the design and production of winnowing machines. In this blog, we will explore the history of the winnowing machine, its design, and its applications in the cocoa and chocolate processing industry. If you have questions after reading this blog, feel free to get in touch with us! Let’s find out now more about the history of winnowing machines.

"New chocolate innovations 2022 and beyond"

In a fast-paced global market, it’s difficult to keep up with today’s everchanging consumer tastes and demands and there are many local and global drivers that are influencing these changes. Brands that stay head lead by emulating credibility, being contemporary and innovative.

The history of winnowing machines

The first winnowing machines were developed in the 18th century in Europe, primarily in the United Kingdom and France. These machines were designed, with the main goal to separate grain from chaff, and they were manually operated, often using a crank or lever to create airflow to blow away the lighter chaff. Later versions of the winnowing machine were motorized and could process larger quantities of grain at a faster rate.

In the United States, the design of the winnowing machine evolved to suit the needs of farmers and their crops. For example, the seed cleaning machine was developed to remove debris and impurities from seeds, while the rice winnowing machine was specifically designed for rice processing. Other machines, like the corn and grain winnowers, were multi-purpose machines that could be used for a variety of crops.

Which different designs of winnowing machines are on the market?

Winnowing machines are typically designed to remove chaff, which is the dry, scaly part of the seed or plant that is not edible. The design of the winnowing and cracking machine depends on the specific application, but most machines consist of a rotating drum or cylinder with a series of fins or paddles. The drum rotates at a high speed, creating airflow that blows away the lighter chaff while the heavier seed or grain falls through a series of screens or sieves. The chaff is then collected and removed from the machine, leaving the clean and edible seed or grain. The process as we explain is easy to project on cocoa processing. We offer a wide range of winnowing machines for the cocoa, chocolate and nuts and seeds industries, from larger installations to some smaller machines.

Mini cocoa winnower machine

Mini winnowing machines are small, portable machines that are designed for small-scale chocolate makers. These machines are typically lightweight and easy to operate, making them an ideal choice for those who need to process small quantities of cocoa beans.

Non-Customized Machine Types

Non-customized machine types are winnowing machines that are designed for general use, rather than specific applications. These machines are typically less expensive than customized machines and are widely available from machine suppliers. They are also ideal for small-scale chocolate makers who need a basic winnowing machine for their operations. So far, you will get an idea that winnower machines come in a variety of designs to fit your special needs.

The applications of winnowing machines in cocoa and chocolate processing

In the cocoa and chocolate processing industry, winnowing machines are used to separate the outer shell or husk of the cocoa bean from the nib, which is the part of the bean used to make chocolate. The traditional method of winnowing cocoa beans involved manually removing the husk by hand, a labor-intensive and time-consuming process. Nowadays, cocoa winnowing machines automate this process, making it faster, more efficient, and cost-effective.

It is clear that cocoa winnowing machines come in different sizes and capacities, from mini winnowers designed for small-scale chocolate makers to larger, high-capacity machines for commercial production. The cocoa winnowing process is a critical step in the cocoa process, as it helps to remove any impurities and ensures that the nibs are clean and ready for further processing. After winnowing, the nibs are typically roasted, crushed, and ground into a cocoa liquor, which is then used to make chocolate.

In addition to cocoa winnowing machines, Royal Duyvis Wiener BV also offers a range of other chocolate processing equipment, including cocoa liquor machines, moulding machines, butter press machines, and chocolate tempering machines. Our extensive selection of equipment allows you as a chocolate producer to streamline your production process and produce high-quality chocolate products with ease.

What are the benefits of using winnowing machines in cocoa processing

Using winnowing machines in cocoa processing offers some interesting benefits for your company, including:

  1. Increased efficiency and productivity: With the use of winnowing machines, the process of separating cocoa nibs from the husk is significantly faster and more efficient than manual methods. This means that you can process larger quantities of cocoa in a shorter amount of time, increasing their overall productivity and profitability. 
  2. Consistency and quality control: Winnowing machines offer consistent and precise results, ensuring that the cocoa nibs are free from husk and impurities. This means that you can maintain a high level of quality control in the products and ensure consistency in taste and texture. In the end, consumers will enjoy your delicious taste consistently. 
  3. Reduced labor costs: One of the benefits is the reduced costs for laborers. Using winnowing machines eliminates the need for manual labor, reducing labor costs for your company. This allows you to invest in other areas of the business, such as marketing and product development. 
  4. Improved safety and hygiene: Winnowing machines are designed to meet the highest safety and hygiene standards, ensuring that the cocoa is free from contamination and safe for consumption. This is particularly important for commercial chocolate producers who need to stick to strict food safety regulations.
