Jackstone Freezing Systems — industrial food freezing solutions

Jackstone is a specialist manufacturer of industrial food freezing equipment with a long history in serving the global food processing industry. The brand is known for designing robust, efficient and reliable freezing systems that help processors rapidly freeze products while preserving quality, texture and flavour — essential for meat, poultry, seafood, bakery and prepared food production.

Jackstone equipment includes a wide range of freezing technologies such as plate freezers, tunnel freezers, IQF systems and crust hardening freezers tailored to diverse production needs.

Who is Jackstone?

Jackstone Freezing Systems has been operating for many decades, building a reputation for dependable freezing machines used around the world. Their portfolio covers various styles of freezers suited for specific applications — from high-capacity spiral freezers to compact plate freezers — enabling processors to maintain product integrity at every stage of freezing.

Their machines are engineered to meet industrial standards of hygiene, energy efficiency and durability.

What does Jackstone do?

Jackstone develops and produces industrial freezing machines designed to deliver rapid and consistent freezing across a wide variety of products. These systems are used to:

  • preserve product quality and texture
  • reduce microbial growth through fast freezing
  • support cold chain requirements for storage and distribution
  • integrate into larger processing lines

Their solutions span contact freezing, airflow freezing and IQF principles to match production formats and throughput requirements.

Jackstone machines & product types

Below is an overview of the core Jackstone freezing machine types:

1. Plate Freezers

Plate freezers use direct contact freezing technology to achieve rapid, efficient freezing.

  • Horizontal Plate Freezers — ideal for flat-packed products where quick heat transfer is needed.
  • Vertical Plate Freezers — space-efficient design offering fast, uniform freezing for packaged goods.
  • Vertical Flat Top Freezers — high-capacity plate freezers with ergonomic loading and easy cleaning features.

Plate freezers are particularly suited for seafood, meat cuts, boxed products and high-value frozen goods.

2. Spiral Freezers

Spiral freezers are designed for continuous, high-capacity freezing with a compact footprint.

  • multi-tier spiral belt systems that maximise freezing capacity
  • gentle product handling to preserve shape and texture
  • suitable for poultry, seafood, bakery items and ready meals

Spiral freezers allow uninterrupted production flow and efficient space utilisation in industrial facilities.

3. Inline Tunnel Freezers

Inline tunnel freezers support continuous product freezing as items pass through a controlled cold airflow environment.

  • high-capacity tunnel designs
  • flexible throughput to match production needs
  • hygienic stainless-steel construction

These systems freeze loose, irregular or shaped products while maintaining consistent quality.

4. IQF (Individual Quick Freezing) Freezers

Jackstone’s IQF freezers deliver rapid individual freezing with minimal clumping:

  • fluidised belt systems for quick separation and freezing of small items
  • adjustable settings for airflow and belt speed
  • designed for vegetables, fruits, rice, fries, meat and seafood

IQF technology ensures high-quality, uniform freezing that supports inventory flexibility and product integrity.

5. Crust Hardening Freezers

Crust hardening freezers are specialised units that gently freeze the underside of delicate or sticky products:

  • creates a thin frozen crust to prevent sticking in downstream systems
  • preserves shape and texture before final freezing
  • ideal for sensitive or high-moisture products

This technology is often used as an intermediary step prior to further freezing.

How Jackstone freezing technology works

Jackstone freezing machines are based on efficient heat transfer principles and engineered airflow or contact freezing:

  • Contact freezing (plate freezers) achieves rapid heat removal by sandwiching products between cold plates.
  • Airflow freezing (tunnel and spiral) uses high-velocity cold air to circulate around products for uniform freezing.
  • IQF fluidised systems enable individual freezing by keeping items separated during rapid temperature reduction.

These approaches help processors achieve consistent product quality, minimise dehydration and improve throughput efficiency.

What is Jackstone specialised in?

Jackstone is specialised in industrial food freezing solutions that deliver:

  • rapid, uniform freezing to preserve taste, texture and nutritional value
  • scalable capacity from small to large industrial lines
  • contact, airflow and IQF freezing technologies
  • durable, food-safe stainless steel construction
  • flexible integration into existing processing systems

Their equipment serves a broad range of sectors including seafood, meat, poultry, bakery, ready meals and frozen prepared foods.
