Camden-based Campbell Soup Co. has closed the sale of Bolthouse Farms to an affiliate of Butterfly Equity, a Los Angeles-based private equity firm, for a purchase price of $510 million, subject to customary adjustments.

The sale of Bolthouse Farms marks the completion of the divestiture of the Campbell Fresh division. Campbell previously announced the sales of Garden Fresh Gourmet and the company’s refrigerated soup business. Net proceeds from the divestitures will be used to pay down debt.
