In a solution cultivation method for a low potassium vegetable, an entire cultivation period from seeding to harvesting is divided into a first cultivation period and a second cultivation period depending on the vegetable to be cultivated. In the first cultivation period, the vegetable is cultivated in a first culture solution containing a first fertilizer for solution cultivation which contains potassium. In the second cultivation period, the vegetable is cultivated in a second culture solution containing a second fertilizer for solution cultivation which does not substantially contain potassium. During the second cultivation period, an air flow is applied at a controlled speed to the growing point of the vegetable.

The system for cleaning fresh and freshly-cut produce is designed to clean produce as soon as practicable after the produce is cut. As the produce falls downwardly, a spray manifold directs a produce-washing liquid upwardly so that the produce-washing liquid directly sprays and impacts the falling produce. The impact of the produce-washing liquid causes the produce to tumble and the descent of the produce is slowed, and consequently the produce is thoroughly coated and cleaned by the produce-washing liquid. In an alternative embodiment, a suspending fluid (preferably air) is simultaneously directed to the falling produce to slow the descent of the produce and further ensure that the produce is thoroughly washed and directly sprayed by the produce-washing liquid.

A system and methodology for rehydrating perishable items (e.g., flowers, fresh food items, such as fruits, vegetables, other produce, and nuts) during storage and transportation thereof. The osmotic rehydration apparatus includes a pressurized chamber, a humidifier, an ozone generator, an electrostatic sprayer, a reservoir containing saline, and an air compressor. The perishable items are placed in the osmotic chamber under positive pressure. A film of saline solution is applied to the surface of the perishable items via an electrostatic sprayer. The saline/chlorine film on the perishable items is dried, and the osmotic chamber is saturated with ozone gas via an ozone generator. The osmotic chamber is then saturated with tiny pure water droplets via a humidifier or an electrostatic sprayer. The pressure within the chamber is raised to a pressure above atmospheric pressure. The osmotic chamber is then placed inside a cooler at a temperature slightly above freezing.

Disclosed is system for inactivating bacteria and/or reducing microbial count on product, in particular a food product, susceptible to microbial presence, said system comprising a processing chamber which is operably connected to i) a means for generating UV-C light, ii) a means for generating hydrogen peroxide vapor and/or means for generating ozone, and iii) a heat source. Also disclosed is a method for inactivating bacteria and/or reducing microbial count on a product, in particular food product, which is susceptible to microbial presence, said method comprising subjecting said product in a processing chamber to exposure with ultraviolet C (UV-C) light and hydrogen peroxide vapor and/or ozone, and heat, for a processing time of between 5-120 seconds, wherein the hydrogen peroxide vapor is present at up to 12% v/v solution, and the temperature inside the processing chamber is maintained between about 22° C. and 60° C.

A method and apparatus is disclosed relating to food processing and preparation in commercial kitchens. The inventive extreme vacuum cooling (EVC) technology and apparatus for food rapid cooling and food flavor infusion can work in ultra low pressure conditions with adaptive chamber pressure control to avoid liquid splash inside the food chamber. The disclosed EVC cooling and food flavor infusion apparatus has a one-unit design for handing small payloads, and a dual-module design to handle larger payloads. It can accelerate the food marinating and brining process with substantial time savings. Using the EVC apparatus, large amounts of meats, vegetables, and fruits can be prepared with various flavor infusion recipes. Plant-forward and high-volume food service kitchens can become more time and energy efficient, less labor intensive, and higher throughput food preparation operations.

An improved system and method for treating, precooling, handling, and packaging perishable products uses a mobile container enhanced with increased capacity refrigeration and air flow to recirculate functional substances including sanitizers, and ripening management and conditioning agents across the surface of perishable products during the precooling step. The mobile container is a prefabricated container or is modified from a standard intermodal container or over-the-road semi-trailer. The enhanced forced air and/or refrigeration equipment is contained within the container and/or mounted on the top and/or side exterior of the container and can accomplish rapid cooling. The mobile container can be located near harvest or facilities with no cooling assets. A combined system using conveyors and operational controls provides automated handling of the perishables from receiving, through precooling and treatment, through processing and packaging, preferably to a MAP process, and then to distribution.
