Grape peeling machine

Types of grape peeling machines

The grape peeling machine is primarily used in the food industry. Several machines can peel the skin of grapes. This is possible without altering the pulp or inner content. The skin of the grape serves different purposes. For instance, it is the main holder of tannins in the grape fruit, which can be valuable when making wine. In another case, some companies and food brands prefer to leave the skin on, as it can boost the nutritional value and fiber content in the food and final produce.

The machine works perfectly when there is a large-scale need for peeled grapes. Manual peeling is not a feasible solution when there is an industrial-scale demand. There are a few types of grape peeling machines that can efficiently peel grapes with precision and uniformity. Here are some of them:

• Grape Peeler

  It is a multi-functional kitchen tool that can remove the skin of the grape with little-to-no damage. It works best when there is a limited quantity of grapes and small-scale production demand. The grape peeler has a curved blade that can gently slide under the skin of the grape. It detaches the skin without applying pressure on the fruit. This allows the user to peel the grape with a smooth motion. The peeler is easy to use, sanitary, and safe. But the main drawback is that it is not feasible for large-scale production.

• Grape Peeling Machine Handheld Device

  The handheld device is manually operated. It can peel the skin of the grape by pressing the button. These devices are small, portable, and easy to use. They are powered by batteries, and some models have a button to change the speed of peeling grapes. Like the hand-held grape peelers, they are not ideal for large-scale production. However, they are better than the hand-held grape peeler since they can efficiently peel grapes without the need for manual effort in every single grape.

• Industrial Grape Peeling Machine

  A few machines can efficiently peel grapes on a large scale. They are made of stainless steel and have conveyor belts. The machine operates by submerging the grapes in boiling water, followed by shock cold water. This process is known as blanching and helps ease the skin's detachment from the flesh of the grape. Once the grapes are in the machine, they are blasted by high-pressured water jets. This all-natural process helps strip the skin of the grape without damaging the pulp. The peeled grapes are then processed further. The machine can be integrated with other fruit processing equipment. It has automatic and semi-automatic features and works at an optimal speed with a high level of efficiency.

Specifications and Maintenance of Grape Peeling Machines

Understanding the specifications for a grape peeler machine helps businesses comprehend the varied applications and capabilities for different settings. Besides this, knowing how to maintain these machines is crucial to ensure they function well for a long time.

• Capacity: This refers to the volume of grapes the machine can peel within an hour or specified time frame, and it usually ranges from 100 kg/hr to 1,000 kg/hr. The capacity of a grape-peeling machine can be suitable for small-scale processes, like making homemade jams, for more extensive commercial use, such as large-scale wine production.
• Power: This machine has different power options, such as electric motors and hand crank, measured in horsepower (HP) or watts. Some machines use a one-horsepower motor and about 350 watts, while some use two horsepower, which is about 750 watts. Machines with higher motor power are more efficient and can handle tougher grapes.
• Dimensions: The dimensional size of a grape skin remover machine determines how much space it will take up, and this means your business will have to create room for it. Such dimensions are 100 cm x 60 cm x 120 cm. Larger machine dimensions are more suitable for industrial-scale processing.
• Material: The peeling component of this machine is made from stainless steel, which doesn’t break, rust, or get corrosive when exposed to materials with high acidity. Because such machines handle food, the peeling surface is also made from food-grade material to ensure food safety and hygiene compliance during processing.
• Function: Some peeling machines slice grapes before peeling, while others peel them whole to ensure maximum yield. Machines that slice the grapes first are more suitable for varieties with tough skins, like Concord grapes.

Proper maintenance of the peeling machine ensures it continues to run fine for long periods with little to no downtime. Make sure the machine is clean before, during, and after use to prevent contamination and food safety compliance. Grime, dirt, and food residue are harsh on the peeling machine's surface and can cause corrosiveness that weakens it. Use food-safe cleaning products to clean any food residue off the machine.

Regularly inspect the peeling machine parts for signs of damage and repair or change any damaged parts to prevent them from causing a whole lot of damage to the entire machine. As indicated in the manufacturer's manual, make sure to frequently lubricate the peeling machine parts so that it moves easily and does not make any loud and awkward noises.
