STiR coffee and tea 53 Roasters Petroncini delivers a variety of convec- tion drum roaster sizes and functionality to meet different needs. Its TT Roasters handle 5-400 kilograms per batch. The forced hot air during the convection pro- cess enhances the process. TT roasters, well suited for small- and medium-size productions, are equipped for roast-profile management. The roast- ers have automatic profile control, tem- perature settings, and roasting cycles that can be replicated for consistency. And they can be configured with green coffee processing units. The Hub's TT 5/10 and TT 15/20 specialty roasters fill the small-batch niche with air convection technology that works well with smaller productions, the company says. The TT 5/10 handles up to 30 kg per hour while the TT 15/20 can accommodate up to 60 kg. Both are available with either manual or profile roasting controls. They also may be powered by either gas or electric heating. Like other Petroncini roasters, these are available with destoners and af- terburners. The TMR roaster is a modular machine that can roast up to 720 kg per batch. This largest unit, designed for industrial use, repeatedly produces consistently roasted beans. Dedicated software manages the roasting profiles with its "pre-drawn time-tempera- ture" that insures there is no more than a two-second variation in roasting times all year long. A single-burner system and efficient heat recovery keep energy consumption low. Handling and storage Once the beans are roasted, it's vital that they be handled and stored to preserve quality and integrity. IMA Coffee Hub offers customizable systems for all production sizes. This includes storage, pneumatic handling systems, rotary distributors, weighing sys- tems, and mixers. Grinding and degassing Before the beans move to packaging, the focus shifts to grinding and degassing. The IMA Group has developed a variety of systems to meet the specific needs of each product, such as ground coffee, capsules, single-dose packs, and vacuum packaging. Single-serve capsules The IMA Group has been synonymous with single-serve capsule machines for years. The Coffee Hub now allows roasters to distribute their blends regardless of produc- tion volumes. The options start with GIMA's 595 capsule filling and sealing machine, a unit that can use both injected and thermoformed capsules at rates reaching 600 capsules per minute. The 595 modular design accommodates a variety of sealing and cutting sys- tems based on materials, capsule type, dosed product, and other considerations. The Spreafico SC Series, meanwhile, helps prepare capsules by cutting, inserting, and sealing filters. SC series machines can be configured to work with different types of capsules, no matter the materials. Setups range from 4-16 lanes with speeds up to 60 strokes per minute.
